If you, however, find a more elegant way or have got a question, please don’t hesitate to post a comment. Both virtual machines will allow you to use Mac OS X Yosemite as a second operating system. So if you experience the same problems, look for a Mac with Yosemite and a recovery partition and create the VM on that machine. Not the most elegant way but at least effective… I created the virtual machine on my MacBook Pro and moved it to the Mac Mini. I tried to install Yosmite from a bootable Mac Installer Stick but I got constantly stuck in the EFIģ. As this would most likely have been resulted in needing to wipe my disc and to restoring everything, I did not go down this path.Ģ. I looked for a way to recreate the recovery partition. I have tried three workarounds for this problem:ġ. It turned out that the problem is that my Mac Mini does not have a recovery partition and therefore Parallels does not show the regarding install option. After starting up Parallels 10 on my MacBook Pro, voila, there was the option (and I was able to capture the screenshot above). I have thought that this would be caused by some legal issue of Parallels 10 with Apple or so. The problem I experience is that there is no option on the install screen prompting me to »Install OS X Using the Recovery Partition«. The window redraw issues I had previously seen were also addressed, with windows now being refreshed correctly regardless if they were in the background or foreground.I’ve came across the problem that i cannot create a new virtual machine of Mac OS X Yosemite 10.10 on my new Mac Mini. When I tested the compiled BeamOff application, I saw a considerable improvement in how fast the VM was now responding. Once it has finished disabling beam sync, it then quits automatically. When BeamOff runs, you should see it appear briefly in the dock and bounce once or twice as it runs. Still the best desktop OS you can get, Yosemite is sleek, beautiful, and brimming with conveniences and new features. JasF posted the source files to GitHub and a compiled version of the application as part of this thread on the InsanelyMac forums. For more details, see below the jump.īeamOff was written by JasF, who developed BeamOff to fix the performance issue he was having with Yosemite VMs. The way to disable it was to use Apple’s Quartz Debug developer tool.Įnter BeamOff, an application designed to do one thing – disable beam synchronization.Once that’s done, the performance of an OS X VM running 10.10.x improves dramatically. We have brought a 100 safe and secure method to Download macOS X Yosemite Virtualbox image, Which you can use to install OS X Yosemite on any desktop or laptop with the help of Virtualbox or VMware. Beam synchronization works fine on Yosemite when running on actual machines, but it is apparently a significant issue when running in a VMware VM.įortunately, the answer to the problem is relatively simple – disable beam synchronization. On investigation, the root cause of the issue was beam synchronization, which is a technique first introduced in 10.4.x to better handle screen redraw and allow OS X’s window management process to be more efficient. These windows were not redrawing correctly when they were selected and brought to the foreground, resulting in parts of windows showing up as being transparent. I also saw redraw issue involving windows that had been in the background and hidden behind other windows. Even ensuring that the VMware Tools were installed did not markedly improve performance. This changed with Yosemite, where the graphics performance in a VM was sluggish and assigning more RAM and processors to a VM did not address the issue. To go along with the convenience, there can be a performance trade-off between VMs and physical Macs, but it’s usually been one where assigning adequate RAM and processors to the VMware Fusion VM usually resulted in decent performance in the VM. 3) Delete all unworthy Snapshots Now & Speed up Mac OS X. Being able to virtualize OS X with VMware Fusion has been a great tool for Mac admins, as it allows them to test out new workflows and configurations before committing them to actual Macs. 2) Now Allocate your system’s Disk Space.
