Macbook Air 2024 beachballing and freezing every few minutes after update to 26.2

1. Why does one analysis say I have 14 MB free while the disk app says 57MB?

14 GB is your amount of free storage. That's what's important. This is critically low.

The 57 GB is Apple's invented concept of "available" storage. It's unimportant and has no value other than confusing people. EtreCheck only includes it because people are likely to be confused. So I figure if I show both, users will understand that they are two different values.

And even if you had 57 GB of free storage, that would still be critically low.

2. Several years ago Apple moved my docs to the cloud, leaving little on the Mac.  This happened on a previous Mac.  Now most docs are both places.  I never moved them back, how did this happen?  Can I set something so they are all in the cloud?

Not sure what you're saying here.

You can configure iCloud Drive (and other iCloud services) to "optimize" storage. The theory with this is that they will try to keep most data in the cloud unless and until you need it. For iCloud Drive, go to System Settings > Apple Account > iCloud > Drive > Optimize Mac Storage and turn it on. If you weren't already using Desktop & Documents, turn that on too.

You have a 250 GB hard drive, so you have to do everything in your power to conserve your storage. Turn on all iCloud optimizations.

If you find any large files on your local hard drive in an iCloud folder, in the Finder, you can control-click or right click on the file and choose "Remove download". This will "evict" that file from local storage. If you ever try to open it again, iCloud will have to download it. But if this is a large file that you don't need every day, you might want to do that.

All these iCloud settings can take a while (weeks) to configure themselves optimally. Most likely, you'll have to force the issue by locating large files yourself and performing the "Remove download" operation.

3. Why is system data 75 MB?  Is this normal?

It's actually not too bad. Most people with storage problems have much more "system data".

4. Why did this suddenly become a problem in updating to 26.2?  Can I revert?

This is one problem that has nothing to do with 26.2. What you're experiencing has been a common problem for a few years now. You were probably right on the edge of noticing and then the 26.2 download pushed you over. That's all.

Unfortunately, a 250 GB hard drive is really too small to be useable. You're going to have to do a lot of extra work to keep the storage in a manageable and useable state.

Just to add to all the very good advise from one and all

Reducing System/Volume/Data is a common question.

How to free up ‘System Data’ and other storage on your Mac from a fellow colleague  @ neuroanatomist

Use another application to see where space is being used  Storeograph  on the Apple Apps Store also from another colleague appearing in your question

Suggest getting an External SSD Drive and start moving your Pictures, Videos, Music and any other large files you have control over, OFF the Internal drive and Onto the External

Understanding iCloud Drive from a well written User Tip from @ Richard.Taylor

There are  two effective ways to remedy this issue:

1. Quick Fix Actions:

For Apple Silicon computers, use Disk Utility to erase a Mac.

Always make a Time Machine backup before proceeding.

Migrate only the user account, not the entire system.

 Reinstall only the necessary applications from the Apple App Store or directly from the developers.

2 - Generally

When the user discovers this issue, it’s likely because the computer’s internal drive capacity is small, such as 256 GB or 512 GB.

For example, the 13-inch MacBook Pro around 2017 offered a 128 GB storage option, and Apple sold these configurations into 2018. 

Unfortunately, the user’s storage needs may have increased since the computer was purchased.

To future-proof the computer, consider spending extra money upfront on a larger drive capacity and adding more unified RAM.

Note - On Apple Silicon and newer computers. The SSD Drive and the Unified RAM are Soldered to the Logicboard and can not be upgraded.

Those drive scores are dismal as others point out:

Write speed: 340 MB/s

Read speed: 1684 MB/s

To sense the scope of your issue, an M1 Macbook Pro 2020 I tested did 3200MB/sec for both scores in multiple tests over a period of about nine months.

Those are GB not MB.

iCloud is for sharing data between devices, not for freeing up larger amounts of space.

3. Why is system data 75 MB?  Is this normal?

Where are you seeing system data at 75MB, or is that GB...?

4. Why did this suddenly become a problem in updating to 26.2?  Can I revert?

No reverting back, requires an earlier Time Machine from before Upgrading to macOS 26.

Then a full erase, macOS install and a restore or migration from that earlier Time Machine backup.

I have a large number of chunk files, all from the same few minutes in 2022 (therefore from my old Mac) I'm guessing i can get rid of them. What are they?

Never heard of the "chunk" file. What's the path to one of those files? If they're from 2022, and you don't know what they are, then you probably don't need them.

Your MacBook Air's internal storage drive is Low on Free space and that is causing low Write speed.

Ideally for your Mac to preform properly, you should have 80 to 100GB of free space.

To free up a small amount of internal storage space Apple's way.

see > Free up storage space on Mac - Apple Support

To free up a considerable amount of internal storage space.

You can move your Photos, Music, Movie Libraries to an external hard drive.

@den.thed nailed the problem. You need to delete files. You should have at least 10% and preferably 15-20% of your internal storage as free space.

Note that deleting files won’t immediately free up the space, you’ll need to run for a day or two before macOS purges the space.
