idecachedeleteappextension quits

Found the solution on Macrumors. Had to open Xcode and let it finished installing whatever – I chose to not install any other components but, it still went ahead and installed something. Closed Xcode and no more crashes from idecachedeleteappextension.

Really, this should not happen. App Store should update Xcode fully when asked.

As for what is causing it try searching on it. How much available space is left on your Mac Studio?

the hd 2tb is about 3/4 full

It is generally a good computer practice to alway keep at least 20% to 25% of the Total Drive Capacity’s as Empty Space.

Allowing the computer to drop below these guidelines may eventually, cause unintended consequences.

There is Purgeable Space and there is Empty Space.

Purgeable Space which is Controlled by the Operating System. When the Operating Systems decides the computer needs additional Empty Space, it will move a portion of the Purgeable to Empty space

AFAIK - there is no User Actions to hasten this transition from Purgeable to Empty Space

It can day or longer before this will occur.

Also running a Mac Studio. IDECacheDeleteAppExtension crashed 4 times yesterday and twice in the last hour today. My 1TB SSD is 60% full – 51GB "purgable". These crashes started after installing macOS 15.

Maybe it has to do with disk space, but that's not the main reason. As others note they have plenty of free disk space. I have a 2Tb SSD on my macbook pro and there is 1.2Tb free. I get this error multiple times nightly and during the day so that makes no sense. I did finish installing Xcode so I will wait and see. And really, 25% free space or bad things happen, how useless is the disk management software.

Anyway, as @Garry Brooke points out, this should not happen, very poor QC and the fact that it's still happening with Sonoma 14.6.1 is just rubbish.

Look, I think the HD free space thing is an absolute red herring. Many gigs free and the error still occurs. Logic dictates it's something else. And the percentages are meaningless. If you have 20% of a 200Gb drive you are looking at 40Gb, on my 2Tb drive 400Gb so makes no sense.

Do you have any reference for that "good computer practice"? Because to me it sounds more like "urban legend" or "old wives' tale". As you can see, many people have the same problem even though they have well over 30% free in their disks.

I have more than half (500GB) free

Thank you! Did the same - so far so good)
