Scratch For Mac Os X

Reinstall from macOS Recovery

Operating systems (often abbreviated as OS) are simulation projects that imitate an operating system.Despite the fact that Scratch is not capable of creating an actual operating system, projects resembling them have been made.
Operating System: Windows 2000 or later, Mac OS X 10.4 or later, Ubuntu Linux 9.04 or later (For other versions of Linux, see the Linux Installer page) Disk: at least 120 megabytes of free space to install Scratch. CPU and memory: Most computers have enough memory to run Scratch 1.4, but very old computers may run Scratch slowly.
Scratch 2 free download - Scratch, The Sims 2 University Update, Boom 2, and many more programs.

Scratch substitutes the program source code for a series of pre-defined instructions that can be dragged and dropped within the development area. Instructions like loops and control sentences like 'if' or 'case' are used to nest the rest of the operations in a graphic form. Each group of commands corresponds to a.

macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu , which is also available in macOS Recovery.

1. Start up from macOS Recovery

To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following sets of keys on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.

Command (⌘)-R

Reinstall the latest macOS that was installed on your Mac (recommended).

Option-⌘-R

Upgrade to the latest macOS that is compatible with your Mac.

Shift-Option-⌘-R

Reinstall the macOS that came with your Mac, or the closest version still available.

You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.

When you see the utilities window, you have started up from macOS Recovery.

2. Decide whether to erase (format) your disk

You probably don't need to erase, unless you're selling, trading in, or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Learn more about when and how to erase.

3. Install macOS

When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the onscreen instructions. You will be asked to choose a disk on which to install.

If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
If the installer is for a different version of macOS than you expected, learn about macOS Recovery exceptions.
If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.

Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

If your Mac restarts to a setup assistant, but you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

macOS Recovery exceptions

The version of macOS offered by macOS Recovery might vary in some cases:

If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available.
If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS that is compatible with your Mac.

If you can't get macOS Recovery to offer the installer you want, you might be able to use one of the other ways to install macOS.

Other ways to install macOS

You can also install macOS from the App Store or Software Update preferences. If you can't install macOS Catalina, you might be able to install an earlier macOS, such as macOS Mojave, High Sierra, Sierra, El Capitan, or Yosemite.
Or create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.

If you are a macOS user who regularly works in programs like Adobe Premiere Pro, Final Cut Pro, and Adobe Photoshop, you’ve probably encountered errors relating to a 'scratch disk.' The most common error is Photoshop’s refusal to open along with the message 'could not initialize Photoshop because the scratch disks are full'.

If you’ve stumbled on this page because you’ve experienced this issue, you’re in luck: we’re going to show you how to easily resolve your scratch disk problem and, as a bonus, keep your Mac clean and performing at its best.

What is a scratch disk?

Before we highlight some solutions, it would be a good idea to have at least a general sense of what a scratch disk actually is. When you are using programs like Photoshop or Final Cut Pro, they require a working space called virtual memory or cache memory. This is where temporary project files are stored and accessed.

For this guide we are focusing our laser sights on Photoshop. After all, it is the most common application. But rest assured that the info we cover will apply to most programs that rely on scratch drives.

Scratch disk is your hard drive space used by Photoshop as virtual memory when there is not enough RAM to complete a task. Photoshop allows you to assign several scratch disks: that way, it has more space at its disposal.

When working with large images and lots of layers, Photoshop is secretly chewing up your Mac’s space by rapidly creating a mountain of project temp files.

It’s important to note that when you set up Photoshop, you will have the option to assign the scratch disks to the drive of your choice. We highly recommend not using your system drive, unless you have no other alternatives.

Reasons behind “scratch disks are full” error

Temporary files are the most significant reason behind the “scratch disks are full” error. They usually mass up in your drive without leaving single evidence of their presence. If you have a habit of force-quitting Photoshop, you may have a lot of temporary files on your Mac. As Photoshop can’t fully close all projects after you quitted it so rapidly, it keeps such files on your machine.

Here are some other reasons that may cause the mentioned message:

Lack of space in the drive where the scratch disk is located
The partition of the disk being used by Photoshop is full
Limited RAM allowed for the Photoshop

What to do when your scratch disks are full?

Mac users receive a 'scratch disk full' message when Photoshop (or any of the other programs) has used up all the space on the hard drive that has been assigned as a scratch disk. This used up space is temporary and separate from your actual project file.

The problem is that Photoshop doesn't always get rid of these temporary files when they aren't needed anymore, which is more like a permanent problem if the user can't find a solution.

So how to clear your scratch disks? Let's find out.

Important takeout: If your HD is full, Photoshop will display scratch disk errors.

1. Clear your Photoshop cache

Photoshop has an in-built solution for deleting specific Photoshop caches. When these pesky caches aren’t removed automatically by the program, they can grow and take up a lot of space on your scratch disk.

To use this tool simply enter Photoshop in Mac and with an image open:

Click the Edit menu button.
Hover your mouse over 'purge' to reveal 4 different options.
Undo, Clipboard, Histories, All. If an item is greyed out, that means it has already been deleted.
Select the specific item you want to delete or select 'all' to delete all of your caches.
You will be warned that the purge cannot be undone, so make sure you don’t need a previous version of one of your projects and then click OK.

A good way to keep Photoshop cache from piling up is running regular disk cleanups. But here is a problem: the cache sits so deep in system folders (and their subfolders) that deleting it manually becomes a pain. A company called MacPaw produced a tool just for this purpose, CleanMyMac X. You've heard of similar tools but that one actually pioneered Mac cleanup.

Here’s how you can schedule regular cleanings with CleanMyMac X:

Launch CleanMyMac X tool.
Click System Junk and press Scan.
Click Review Details to deselect the data you want to keep.
Hit Clean to clean up junk files.

Just let it do its thing. That way, you’ll never forget to clear Photoshop cache and tons of other system junk on your system.

You can download CleanMyMac X free version and see how it works.

How your Scratch drive is filling up, an example from Sketch

Along with Photoshop, Sketch is another app that keeps temporary versions of projects on your disk. And it eats up a whole lot: from 60 to 220 GB on average.

Each time you press Command + S some space is wasted away from your Scratch drive. Say, your file weighs 23 mb. Then, 7 temporary editions would increase that size to 161 MB. This problem hasn’t been widely known until recently, but, luckily, there is an automatic solution.

CleanMyMac’s System Junk module lists Documents’ Versions from Sketch and other similar apps. You can keep the final and the oldest version of a project and delete all revisions in-between. Voila, you’ve got free space again!

2. Delete your temp files

When it comes to wasting space on your scratch disk, the worst culprit is often Photoshop's own temp files. If Photoshop isn't going to get rid of them, I guess you’re going to have to do the job yourself.

To find them you'll need to look for files that begin with 'pst' and then a string of numbers followed by the file extension '.tmp'. Do a search for 'Photoshop Temp' with a space between the two words.

You can just search your scratch drive but to make sure everything is found, rather perform the search on the entire computer. It may take a couple of minutes for the search to complete, so pop into the kitchen for a quick snack while you wait.

When you return, you should have a long list of files. If your work is saved and the program is closed, you can safely delete these files and watch as your scratch disk space is reclaimed.

3. Clear your disk space

If you don't have another drive or don't want to buy one, then it's time to do some spring cleaning. Look at the drive contents to see if you can delete anything you don't need. Is there storage space that can be cleared? Usually there is, so go ahead and delete your old files and free up some space.

Alternatively, you can simply transfer files to external drives, DVDs or cloud storage solutions like Dropbox and iCloud.

Take a look at our How to Clean Your Startup Disk (10 Ways). Inside we have lots of practical advice for macOS users who want a clean drive that performs well. Even if your scratch disk isn’t your startup drive, and we hope that is the case, there are many tips to help you spring clean like a pro.

Notice for macOS Sierra (and higher) users:Users of macOS Sierra might be aware that Apple has added new tools to 'help' manage storage space. If you navigate to Apple Menu > About This Mac > Storage tab you will see the new Sierra bar graph.

If you click on 'manage' you will be taken to the new tools. While there are some truly helpful elements, like using Optimized Storage to customize what email attachments download to your Mac, most of the tools just move junk from one place to another place.

Because a lot of these processes are automatic, Sierra users might not be aware of what the OS is doing on their behalf. If it sounds like a good idea to have macOS deciding what files to send to iCloud and what iTunes videos to remove, go for it.

For everyone else, we’d recommend turning off these tools or at least making sure you understand them fully before turning them on.

It can be challenging to check and analyze all contents of your disk space. Luckily, some tools can provide a disk scan and can save up lots of space on your Mac. Apps notarized by Apple is best for this job. CleanMyMac X, the app I talked earlier about, has a Large & Old Files feature, which finds and removes massive files stored on your Mac.

4. Change your scratch disk

If the disk being used is nearly full, change the directory for a more spacious one. Then, restart Photoshop. You can change the Scratch Disk location by pressing Command + Option when launching Photoshop. It can be a hassle but if you keep an eye on the available space on your scratch disk, you can do something when space is becoming limited. It’s also worth noting that problems don't just occur when the drive is completely full, hard drives should ideally never be above 85% capacity. Pass that threshold and problems will be just around the corner.

So, you've identified rapidly depleting free space on your Mac hard drive — now what? Well, it may be a good idea to change your scratch disk to another drive in your system (just not the system drive, as that is one drive you really don't want to slow down). If you don't have another drive, you could purchase one, with SSD being the best option for Mac OS X scratch disk purposes.

Follow these steps to change your scratch disk in Photoshop:

Click on the Photoshop menu.
Go to Preferences and then Scratch Disk.
Tick the checkbox to select or remove a drive as the scratch disk.
Click OK.
Restart Photoshop.

You can change the Scratch Disk location by pressing Command + Option when launching Photoshop

5. Consider buying a new SSD

The scratch disk problem happens because of 2 simple reasons: lack of RAM, and lack of HDD space. Both can be addressed if you buy a Thunderbolt SSD (solid-state drive) to use as your Scratch Disk. By today’s standards, 60 GBs should be enough.

Buy an external SSD to use as a Scratch Disk. 60 GB should be enough.

6. Follow the 15% rule

Not strictly a rule but rather a common practice states that you should keep at least 10-15% of your disk space free at all times. If your HDD size is 256 GB, your lower limit is 25 GB. You’ll have enough room to render your Photoshop files, save multiple project copies, etc.

Loud fans noise is a sign your CPU is overloaded and approaching its carrying capacity.

7. Free up RAM in Terminal

When Photoshop gets paralyzed due to lack of RAM, there is a command you can run in Terminal.

Open the Terminal app (find it in the Launchpad).
Paste in: sudo purge
Then, enter your password.

At first, you may not see the difference, but you’ve just flushed your RAM, releasing all the files kept in virtual memory. There are a few more ways to free up RAM, check out them too.

You can also download CleanMyMac (get free edition here) and use its Free UP RAM command.

Install the app and click on Maintenance.
Select Free Up RAM and click Run.

You can apply this trick anytime to unfreeze an app. Also, check out the other tools in the Maintenance section. They will help you take some load off your Mac’s memory.

8. Search for hidden files in your Photoshop folder

Some projects’ leftovers are invisible and yet take up lots of space. There is a shortcut combination to display hidden files in whatever folder you are. So, open your main Photoshop folder and click Command + Shift + Period. If you find any greyed out folders, check their weight.

To see hidden files in any folder, press Command+Shift+Period.

As you see, there are many methods to solve “the scratch disks are full” error. There is also one more way to reorganize data on your Mac and save up some space. Disk defragmentation gathers related items and lets you delete unneeded data as well as leftovers. Note that the latest macOS doesn’t need to be defragmented as Apple has provided it with in-built utilities, which remove fragmented files automatically. So, defragmentation may only work for you if your Mac’s running the OS version earlier than OS X 10.2.

The 'Scratch Disk Is Full' error fixed!

If you followed this guide there is absolutely no reason why you should ever have to deal with the annoying 'scratch disk full' error again. Next time you want to create something amazing in Photoshop, you should experience something new - a Photoshop that runs so smoothly it practically purrs.

Whether you solve the problem yourself or let a great piece of software like CleanMyMac X do it for you, just make sure you clean up your scratch disk. Your Mac will thank you for it*.

*Not literally. That would be weird.
