Thanks. My hard drive with my photos, documents and logic files on it has 1TB (definitely enough). Could I use that or would I need to format the drive first? If, so I wouldn't be willing to do that, and I don't have any other drives...
I've now binned the aerial companion file and another file which shouldn't have been there.
I also found this (which came with VirtualBox) which I got rid of just now:
Launch Daemons:
[Not Loaded] com.BlueStacks.AppPlayer.bstservice_helper.plist (Not signed - installed 2021-04-11)
Executable: /Library/PrivilegedHelperTools/com.BlueStacks.AppPlayer.bstservice_helper
VirtualBox is completely gone now - Was that supposed to lower my RAM? It's still around 40% with no apps open (ATM 70% with 2 safari tabs and finder).
Is there anything else on that EtreCheck I should change? Any other things I should remove to improve Mac performance?
You said in a previous post that my mac was probably struggling as (without me knowing) it was running an old version of VirtualBox in the background. Will my mac be quicker now tis gone?
