Most of us are keen to update to a new version of macOS as soon as it is available. macOS Big Sur has been out since November 12, still, many users couldn't update their Macs straight away. It’s very frustrating if you see a message telling you that you don’t have enough space to install the new macOS. Don’t worry, though. There are lots of things you can do to fix it. We’ll show you what they are in this article.
If you can’t get a larger hard drive for your portable Mac, the easiest way to get more storage space is to get rid of stuff you don’t need. To start the process, consider the following. Your Mac hard drive consists of disks (or partitions). Each disk (or partition) has your Mac data on it, which consists of your operating system, applications, etc. Most Mac users have just one disk but power users may have two or more. Let’s look at an example of a Mac with only one hard disk: Your Mac's hard drive is 500GB.

How much space do you need for Big Sur?
While the installer for Big Sur takes up less than 16GB of space, you should make sure that you have at least 20GB of free space on your startup disk before you try to download and install it. The more free space, the better. Your Mac uses disk space to store temporary files and provide storage for active apps and tasks (which is what RAM does), so you should never be running with almost no disk space left.
CleanMyMac X makes it very easy to free up disk space on your Mac by identifying junk files and allowing you to get rid of them with a click. It can also detect large and old files and show you the files taking up most space and uninstall applications.
How to free up space for macOS Big Sur?
Complete the following steps to ensure your Mac is ready to update to Big Sur.
1. Backup your Mac
Back up all files and data that are stored on your Mac. Preferably twice to different locations. While upgrading to Big Sur is safe, you never know when something might go wrong. If you use Time Machine or another backup tool, run a manual backup just before you upgrade. Exfat format mac and pc. And, if you can, clone your startup disk to an external drive, too.
2. Free up disk space using CleanMyMac X
If you don’t already have CleanMyMac X installed, download it for free here. This tool will help you clear some space and delete large and old files quickly.
Launch CleanMyMac X.
Choose System Junk in the sidebar and press Scan.
When it’s finished, press Clean to free up space, or Review Details to find out more.
3. Get rid of large and old files
Media files usually gobble up a large amount of disk space. And the worst thing is they are scattered around Mac’s folders, making it difficult to find and remove them. CleanMyMac X proves to be useful here:
Choose Large & Old files in CleanMyMac X’s sidebar.
Press Scan.
When it’s finished, use the middle column to filter files by type.
Check files that you want to delete.
Press Remove.
4. Use Apple’s built-in storage management tool
Apple has provided a method for you to manage storage by showing you what is taking up disk space and making recommendations for deleting. It’s not as quick and easy as CleanMyMac X, but it can help you save disk space. Here’s how to use it.
Click on the Apple menu and choose About this Mac.
Select Storage and press Manage.
In the Recommendations section, review each section in turn.
Now go through each of the sections in the sidebar.
Delete files or take further action, depending on what you choose.
5. Delete local Time Machine snapshots
There is one other thing you can try if you keep getting a message telling you that you do not have enough space to install Big Sur. You should only try it if you are sure there is enough space on your startup disk and that the message is wrong. And it will only work if you use Time Machine to back up your Mac.
Time Machine stores local snapshots on your Mac. Your Mac is supposed to count the space used by snapshots as free space, which is why it looks like you have enough space for the installation.
However, it seems that the installer may not realize the space is free. The solution is to delete the snapshots. This won’t remove backups on your backup disk, just snapshots on your Mac.
Open Time Machine from System Preferences. Uncheck Back Up Automatically and wait some time till Time Machine deletes snapshots. Then you can turn Time Machine back on.
If you’re familiar with Terminal, you can try deleting local snapshots manually.
Go to Applications > Utilities and launch Terminal.
Type: tmutil listlocalsnapshots /
You will see a list of snapshots that look like this: com.apple.TimeMachine.2020-10–09-002010.local
To delete a snapshot, type: sudo tmutil deletelocalsnapshots
Then type the date part of the snapshot name. For example: sudo tmutil deletelocalsnapshots 2020-10–09-002010
Type Return and repeat for each snapshot you want to delete.
Hopefully, this helped you free up some space and update your Mac to the latest OS. If you're just preparing your Mac for the upgrade, don't forget to back up your data before you start clearing space. So you won't be afraid of losing anything important.
System cleanup in one click

Clearing a scratch disk on your Mac may not be a problem you’ll run into often, but those working in apps like Photoshop should understand exactly how to solve for the problem when it pops up. Intensive programs like Photoshop, Premiere Pro, and Final Cut Pro often serve this error up, and it can be really confusing.
Here, we’ll show you how to clear scratch disk on Mac, how to empty scratch disk for use, why Photoshop scratch disks are full, and how to better manage memory to reduce or eliminate the frequency these popups occur.
What is a scratch disk?
Think of a scratch disk like a scratch pad of paper. You use the scratch pad to write down notes for something; maybe it’s ideas for a book you’re writing, or sketching some illustrations by hand before testing the waters in a design app.
Scratch disks work the same way. Large, intensive apps need a bit of hard drive space to use as virtual memory when there’s not enough RAM to finish a task. Like a scratch pad, it keeps things there temporarily while it performs process-heavy tasks like editing videos or photos with many edits and layers. Though these files are temporary, they need a place to live – the scratch disk.
What causes the scratch disk error?
The main reason you see ‘Photoshop scratch disk full’ errors are temporary files. If you force-quit apps like Photoshop often, temporary files don’t disappear. The app thinks you may want to use them later on, so it saves them. These files may not show up as occupied memory, either, which adds to the confusion as to why you see the error message.
Other reasons you see the error is the drive where the scratch disk is located is out of space; this is most frequent when your Mac’s storage is too full. Similarly, the partition Photoshop or other apps uses may be too full, and a limited amount of RAM available to the app may also cause this error.
What Do You Do When Scratch Disks Are Full?
When you see ‘Photoshop scratch disk full’ Mac computers have no good recourse for solving the issue. It won’t automatically clear disk space, or create a unique partition so the problem doesn’t occur. You have to know the methods for clearing a scratch disk yourself.
