    Hello, I am running Parallels Desktop 20 for Mac ( Pro ) on an M1 Pro with 16 GB memory, with the latest Sequoia version of Mac OS.

    Because of the nature of my work, I need to use Virtual machines, so I am running Mac OS guests, also running the latest version of Sequoia.

    I use Jetbrains Pycharm Professional for alot of my work. It works perfectly fine on my computer, but the performance is horrible on a Mac OS guest. The poor performance is mostly when using dialogs such as Preferences / Settings but even scrolling in code is poor.

    I am using he recommended setting of 4 CPU / 6 GB of ram. I have also tried manually increasing to 6 cpu and 8 Gb of ram. but there is no difference.
    The activity monitors on both the host and the guest seem perfectly fine. In fact for the most part only the efficiency cores are being used.

    I know my machine is a little light on specs, but before I spend a ton of cash on an M3 or M4 I would like to know if there is a setting I should consider trying.

    Thank you

    Hello,
    I'm experiencing similar performance issues, even while working on a machine with an M3 Pro chip and 36 GB of RAM. Scrolling in PyCharm is particularly sluggish, and while VSCode performs slightly better, it's still far from smooth. I've tried increasing CPU and memory resources, but unfortunately, there's been no noticeable improvement.

    I guess i will stick with vim for now. Maybe I should make a service request.

    I open a support ticket with the same issue as you have (latest Pycharm, latest Parallels) and they asked me to run the "disk first aid" from inside of the virtualised MacOS (not the Host MacOS). And we found out that the "DATA" disk is broken. It seems to be the rootcause. When I tried to run the disk first aid again in the recovery (which is being recommended by the first aid itself after finding an issue with the disk), the first aid was still not able to fix it. I am still vaiting for the reply from the support about any other ideas, but as a first step, could you please run the first aid too and check whether you have the same issue?

    I ran first aid as you showed, but there were no errors detected.

    I ran First Aid, and no errors were displayed. The strange thing is that I have two Macs with the same specs, and I noticed a significant performance difference in the same version of PyCharm between them. I'm not sure why this is happening. I ran First Aid on both, and no issues were found.

    @JohnD102 are you using a magic trackpad or something like this? Because now I'm switch to MX Master 3S and it's working perfectly :-O

    No. Mostly i just use my macbook pro directly. Sometimes I do use an MX Keys keyboad and MX Mouse. But I don't see any difference either way.

    well, the aid disk didn't help me neither. I have a support ticket open and they are providing some ideas so once I will have some conclusion, I will let you know, guys.

    You are right, the issue really seems to be linked to using the external mouse. Once I disables mine on the host macos, the issue with lagging disapeared. And sometimes I had to disable the BT completely on the MacOS, restart the VM, enable the BT, but disable the external mouse - works perfectly. I have Apple Mouse at home somewhere, plus the trackpad, so I will try to use those and I will let you know if doesn't work also for those. I had the issue when using the Trust mouse.

    This is the reply from the support team. I advice you to subsrcibe to their channel if you are not already.
