Parallels 17.1.3 Update - Coherence Mode Not Available

I have installed the latest 17.1.3 update this morning and now my VM resolution is unusable as it is locked to 1024 x 768. Coherence mode is not available either.

I am running Monterey 12.3.1 on a 27 inch 2020 iMac.

I have uninstalled and reinstalled the Parallels Tools and restarted the VM as well as the computer and this does nothing.

 

I should also add that I am using a Mojave VM.

 

I have downgraded to 17.1.2 as there appears to be a few posts on this version reporting issues with Mac VM's.

 

same here.. the upgrades are not solving bugs. they are adding new bugs..

 

Hello @FabriceK, Please uninstall Parallels Desktop and download 17.1.2 from this link https://download.parallels.com/desktop/v17/17.1.2-51548/ParallelsDesktop-17.1.2-51548.dmg and downgrade. Thanks, Parallels Team.

 

Disappointing that this issue wasn't caught prior to being released given the extent of the Mac OS versions that are affected.
I rely on Parallels on a daily basis to run 32 bit apps on Mojave and from now on will have to check the forums prior to applying any updates.

 

If only I had read this thread before installing 17.1.3

macOS Catalina VM unusable now, will have to uninstall Parallels Tools from Win11 and macOS VMs and downgrade to 17.1.2. Grrr...

 

After experiencing the lost productivity of upgrading to 17.1.3, and back to 17.1.2, I ain't going first!
In fact, I'll wait a while...

 

With all due respect, I'm not going to upgrade to 'check' and just need to know if the issue has been fixed or not.
I don't have the time to deal with broken updates.

 

I'm running Parallels 17.1.4 on an M1 Max Mac and have two ARM VMs, Windows 11 and Ubuntu 20.04. Coherence mode is grayed out on the Ubuntu VM, but works fine on the Windows VM. Perhaps there is something wrong with the Ubuntu VM, but based on all the comments here I'm not too confident that that is the case. I'm actively using these VMs so I do not have the time right now to do anything drastic, but I just wanted to make my experience here known.

I've bit the bullet and upgraded to 17.1.4 during my lunch hour.

I'm happy to report, the resolution and coherence issue seems to have been resolved.

 

That's good to know; thank you for the update.

 

Hi, I'm running Parallels on an Apple M1 Ultra with 128gb of ram. I noticed Parallels caps the ram in half for the virtual Windows 11 install. Is it possible to utilize more? Also, Im unable to utilize both my Apple Studio Display monitor and Dell monitor as dual screens. Also, I unsuccessful with entering coherence mode. Can you please help and thank you!

 

Hello @IanC20, It is not recommended to allocate more than half of the RAM size of MAC to Windows virtual machine as it may affect the performance of Mac or even crash the Mac. For coherence issues, Please try to reinstall the Parallels Tools by referring - Parallels Tools manual installation and check. You may also reinstall the Parallels Desktop for Mac once. Kindly elaborate more on the dual-screen monitor issue for further assistance. Thanks.
