Clearing out storage (system takes 60%)

[espegelan]

Hi,

I've already read a large amount of forum posts about "System" holding up a large part of the storage, and I've tried every tip I found so far. But most posts and articles blames High Sierra and the Time Machine issue.

I'm running the latest Mojave 10.14.2 on a mid 2015 MacBook pro. My time machine has just backed up, and I've deleted the local snapshots right after the backup. So at least I don't think it's Time Machine making the issue. I've also been through the User Library folder to look for unusually large folders, with no luck.

I have to partition my mac with bootcamp, so I need as much space I can get. Any tip of how to clear up "System" would be highly valued. Would it for example help to format the hard disc (really don't want to do that).

Thanks!

She won't win any awards for prettiest application, but it does a very simple breakdown of what's taking up space on your machine. Can you screenshot the results before deleting anything please, just so I can ensure it's safe to delete?

Sorry, forgot to do any screenshots, but this was a great tip! Thank you! I'm using a lot of Adobe software, and that have really taken a lot of cache space! Adobe Lightroom, an app I uninstalled a long time ago, had 87Gb of cache alone! Unbelievable..

Also try DiskWave:

(it's free)

Once you have it, open it.
Go to preferences and set normally-invisible files to be visible.

It will show you what is using the most space.

Questions:
Do you use Time Machine?
Could the problem be with "local backups" or "local snapshots"?
