I cleared my system to install the BigSur beta:
So I have 62 GB free space.
But when Im in the installation process its shows the following:
Just 28 GB free space. How can I fix this?
when I look up my HDD via finder it shows me:
So that 34 GB should be purgable. But how to delete this stuff since my recycling bin is empty.
解决方案
I found a solution: I just created a new APFS parition and reserved as much space as possible. Then the space which was shown as purgeable was deleted automatically. After that i removed the partition again and had all the free space.
其他提示
I think there is a problem with your startup drives... Just boot into Recovery Mode and run First Aid.
NOTE: First Aid will temporarily lock the startup volume.
Time machine local snapshots have been known to take up lots of purgeable disk space. Try entering this in Terminal.app
tmutil listlocalsnapshots /
if you see a list of things printed, those are likely using up your space. They are programmed to remove themsleves as your space fills up. Here is a thread with more info on this topic.
If you just want to remove them, you can run this command
for d in $(tmutil listlocalsnapshotdates | grep "-"); do sudo tmutil deletelocalsnapshots $d; done
and then after a few seconds go over to Disk Utility.
