[BUG] version 20 is unusable in Sequoia: high cpu on idle, heats mac. reverting to v19 works fine.

Hi,
The mac client goes 100% cpu usage when doing absolutely nothing (no remote connection opened)

Could you troubleshoot and give some workaround?

Activity Monitor sample: Sample of Parallels Client.txt

 

using the AppStore latest version. not having any other parallels software (just the client as a RDP client). please don't download the uploaded sample unless you really are able to understand it, as it has a limit of 100 downloads (and I think it expires in 30 days) - but it can be previewed in the site without counting as download

 

oh, looks like terrible coding practice: it wants to check for updates (I think) and somehow it fails then it tries endless in an immediate repeated infinite loop

sample from log show. an insane amount of log for a single second

full log since app start until it goes crazy:

this is all it logs on verbose on it's own UI settings. erased the app store and tried the pkg and behaves identically.

I dual booted to an old Sequoia beta that I haven't used recently, and there I had the previous App Store release version 19.4.3 build 25221 (btw, why do app store version is not exactly the same as about menu?). I rechecked by launching that version booting back to main Sequoia official stable release, and both work ok without high cpu usage.

Ironically, the one supposed to introduce support for macOS 15, in fact BREAKS support for macOS 15, and the older one DOES WORK for macOS 15... /facepalm

 

fwiw, I still do see the same error messages but at such a lower rate that the app does not go up to cpu
