    Hi everyone,

    Before to buy Parallels 12 for Mac, I would like to know if it is possible to make a virtual MacOS 10.12 Sierra (guest) in a host MacOS 10.12 Sierra ?

    Thanks for your answers everyone.

    Hi,
    I tried the trial version of Parallels 12 and I was able to create a macOS Sierra guest machine.

    Hello TomyP. Yes, it is possible to run MacOS 10.12 Sierra as a guest machine or virtual machine in a host MacOS 10.12 Sierra. Please let us know if you have any query.

    TomyP, I've recently upgraded to MacOS 10.12 Sierra using host and ran PixlRec app - it worked fine and so will Parallels 12. Go for it :)

    Yes you can BUT see caveats below (most are stupid and require Parallels to get off their collective backsides and do something):
    1. Default disk size is 67Gb
    2. You can change the disk size, however you CANNOT change the partition size in Parallels even at create time (stupid? Yes...)
    3. So you can have 1Tb allocated disk space, you still get a 67Gb partition
    4. To change the partition size you need a hack to convert HFS+ partition to coreStorage, diskutil size change, convert back to HFS+
    5. You can try everything within Parallels to change the partition size, but will end up with the Parallels KB article and support? advising it cannot be done within Parallels
    6. There is currently an issue with Sierra Guest VM randomly freezing, Parallels have not responded to the forum posts, it's not isolated to one person
    7. So far the system seem to unfreeze, but it is random, disruptive and freezes at times for several minutes
    8. Coherence doesn't work with macOS VM (as far as I can work out)
    9. There are issues that make the Sierra VM unworkably slow, mine was like that, but I fiddled (not sure what I did, but do remember adding 8Gb RAM to the VM)
    10. Parallels DO NOT know what is going on, here's two lots of contradictory advice from Parallels support:
      1. Do not exceed the recommended number of CPUs or RAM
      2. Give the VM half the Physical RAM and half the Physical CPUs
    When working and not freezing, Parallels with a Sierra Host and a Sierra Guest seems to work very well. The tech support to address significant usability issues in a timely manner just isn't there. Parallels support is seriously lacking in this regard. It has been noted that the best advertisement for VMware Fusion is Parallels support and yes, Fusion does run a Sierra guest with a Sierra Host and it does allow you to resize the guest partition on startup.

    I can no longer install Sierra (10.12.5) on Parallels 12 (Version 12.2.0 (41591)). When I use an iso image or the ESD I get the following screen:

    I made the ISO after this manner: https://apple.stackexchange.com/a/253644/13220

    @PaulChris@Parallels odd, you should have seen the image just fine. You can decide whether to reply here or in the other thread wherever you feel is more appropriate. I figured that perhaps I should split it out into a new topic since it was kind of not the exact same issue as this one, but it's your choice. Here's an imgr.com link: http://imgur.com/VNVbylo

    PixlRec app has done the work after updating the Mac. I got the solution from here now it's working on my PS4 device. Thanks

    You probably getting this error because of some important code missing in the directory. Have you tried PPSSPP Emulator for MacOS 10 and MacOS 12?
