Apple today was kind enough to reward it’s loyal beta testers with early access to the GM Candidate build of OS X El Capitan.
In an email, they advise the following to install:
[…] to install the GM Candidate. Go to your Purchased tab in the Mac App Store and click the Download button next to OS X El Capitan GM Candidate. When your download finishes, the installer will automatically launch. Follow the onscreen instructions to complete installation.
And that’s fine and dandy and all if you want to install that on your Mac. But what if you just want to try it out without taking the full plunge on your main machine?
Rather than clicking the ‘Continue’ button and upgrading your host Mac, you can quit the installer from the Menu Bar, or with the keyboard shortcut Command + Q.
Once quit, the installer leaves a just-over-6GB installation file in the /Applications folder.
Before we can install in Fusion however, there’s a bit of a gotcha that Apple surprised us with in regards to their installer. The installer will hang with a white apple and a black background when the progress bar is almost complete. We’ll be releasing a patch, but for now we have a fix.
This quick workaround comes from one of our lead developers, Michael Udaltsov, mentioned on the forums:
To work around the problem, you have to replace:
“VMware Fusion.app/Contents/Library/Create Mavericks Installer.tool”
with a modified version available here.
Once downloaded, unzip the file and you’re left with a ‘Create Mavericks Installer.tool’ file. We’ll drag that to where it needs to go.
First, we have to get into the VMware Fusion Package Contents by right-clicking (or control+click) the Fusion icon in the /Applications folder and selecting ‘Show Package Contents.
It’s a folder like any other, so get into the Contents > Library folder…
Drag the tool we unzipped over the old one…
And get some warnings when we do it, naturally since we’re messing around in the /Applications folder…
And with that done, we can get to installing El Cap!
To begin, in the Virtual Machine Library window, just click the ‘+’ button to add a new VM:
And then drag the Installation image from Finder onto Fusion
Once the installer kicks in, it’s pretty much auto-pilot until the standard Apple first boot stuff.
Click through the first few steps of the installer and the rest is hands off until you’re asked to sign into iCloud.
If you have your host system backed up with Time Machine somewhere, you could even use that to make a copy of your host Mac into the VM, so you can really check if your apps and workflows are going to continue to hold up with Apple’s new OS.
(Of course, you need sufficient disk space for that, so be mindful!)
When the installation is all done and you’re at the desktop, remember to install VMware Tools for optimal performance.
Click through the tools installer and reboot the VM.
And there you have it! The latest and greatest from Apple running in the latest and greatest from VMware!
