    Windows 10 Update won't allow upgrade to Windows 11

    It seems you need to wait some random time before Windows Update recognises that things have changed! In my case after 3 days, it changed its mind and now says that it can run Windows 11.

    Windows 10 Update won't allow upgrade to Windows 11

    I have Parallels Pro 17.1.2. My Win 10 VM is up to date with updates. TPM is enabled, Secure Boot is on, BIOS is UEFI, all confirmed in the VM. PC Health Check says everything is ok (all requirements met) but Windows 10 upgrade says that the PC doesn't meet minimum requirements and I have no...

    Issue with Parallels, Ubuntu VM and the CD-ROM

    That's great to know, thanks. I'm not that familiar with Linux so I'll await a fix released through the normal software update but it's good to know it's fixed.

    Issue with Parallels, Ubuntu VM and the CD-ROM

    Sorry, I'm still not clear. Are you saying that you've found references to that bug that cause different effects on different platforms, including the one I describe above - can you link? Have you patched and recompiled the 5.11.0.34 kernel to prove that it fixes the slow boot? If not, then...

    Issue with Parallels, Ubuntu VM and the CD-ROM

    Could you explain a little more - perhaps there is something in that thread that is related to this issue? That problem seems to be related to the cd-tray being ejected at boot time when a CD was expected but had been removed post hibernation and before resume. I don't see how it relates to...

    Issue with Parallels, Ubuntu VM and the CD-ROM

    Recently, the boot time of my Ubuntu VM increased to over 2 minutes from circa 10 seconds. This was in Parallels 16 but also occurs in Parallels 17. I have traced the issue to a combination of the following: Ubuntu 20.04 kernel 5.11.0-34-generic VM configuration CD-ROM = disconnected. With...

    Parallels 17 + Ubuntu 20 crashing every time

    Also, if you want to boot into an older version of the kernel, press the ESC key when booting not the SHIFT key (at least in Ubuntu!) then take the advanced option displayed to you. Don't select a recovery version of the kernel.

    Parallels 17 + Ubuntu 20 crashing every time

    NOTE: I booted into an older kernel version with CD/DVD = disconnected and there is no problem. There is some interaction between Parallels and 5.11.0.34 kernel that is causing an issue.

    Parallels 17 + Ubuntu 20 crashing every time

    I have Ubuntu 20.04 and I have a similar problem in 16 and, now, 17: it takes 2 minutes to boot and that gap can be seen in dmesg output. Until recently, it was fine but I can't tell if it was a Parallels update or a kernel update or what. The information you are providing above seems to be...

    Understanding Snapshots, SmartGuard and Time Machine

    If you want to backup your VM with Time machine, do not exclude it. If you want to back it up some other way, then exclude it. Smart guard automatically creates snapshots periodically so that Time Machine doesn't need to back up an ever increasing VM. When a snapshot is created, it will be...

    Understanding Snapshots, SmartGuard and Time Machine

    I want to make sure I understand what is happening with these features - unfortunately, many links I try and follow just lead to a "This content is outdated" message. Snapshots are just point-in-time copy of a VM's state when it is taken. So, for example, before making major changes to a VM I...

    Mac crashing when using Parallels

    In my case, I tracked it down to the Arduino plug in that is installed when you want to do development on the IDE. In V14, it was terrible and caused issues all the time - only with Parallels, nothing else. In V15 initial release, it was still a problem but a point release of Parallels...

    USB2.0 device needs disconnecting/reconnecting after each use

    I've been working with a microcontroller board plugged into USB with a Win10 guest for quite some time, developing and testing software. The compiler/debugger can connect to the board for development purposes with no problem. However, since updating my Mac to Catalina, after each debug session...

    Parallels 15 sometimes freezes host system, sometimes won't start on mojave

    I have reported the details below to support but add here for the benefit of anyone else who may be having problems. I have isolated the cause of the issue. As mentioned previously, using Parallels eventually causes my iMac 2019 to become catastrophically unstable leaving me no option but to...

    Parallels 15 sometimes freezes host system, sometimes won't start on mojave

    It's crazy - it crashes Mac even if no VM is running. I left Mac for a couple of hours, went back, wouldn't exit screensaver and eventually spinning beach ball appeared. Had to hard cycle the machine. It is reproducible; have Parallels Desktop and/or Parallels Tools running (with or without...

    Mac crashing when using Parallels

    This is still going on, even with a new iMac and an upgrade to v15. I can reproduce it every time: start Parallels Desktop and wait a variable amount of time, eventually it will happen. I can't create a report as the Mac is not responsive. I don't even have to have a VM running, just the...

    Parallels 15 sometimes freezes host system, sometimes won't start on mojave

    This is happening to me as well. Also happened on V14. I don't understand how to create a report if the whole system has frozen - I can only hard boot the iMac as it doesn't respond to anything else - I've never left it for an appreciable period of time, e.g. 1 hour. It's not at-will...

    Mac crashing when using Parallels

    Since installing Parallels, my iMac has required hard re-booting 4 times now - I've had it installed around 3 weeks. It does this even if a VM is not running, but also when it is (Windows 10.) I'm getting pretty sick of it now as it's causing big problems for me. I don't understand how to...

    Repeated Corrupt .PVM file

    Thanks. I think I will just run those updates on the basis that the download image for June must be up to date with correct fixes. The Update Assistant you refer to above just seems to be a link to update to May 2019 build or to download a tool to create installation media, neither of which I...
