I'm running Windows 10 Home in a VM under VMware Fusion 8.5.3 on macOS Sierra 10.12.2. Machine is MacBook Pro (15", Late 2016).

I shut down the Windows guest, and through its settings, attempted to expand the disk from 60GB to 150GB. I have 300GB+ available on the host.

So far, this is what I've been looking at for about 20 minutes: enter image description here

How much longer should I wait before giving up? And, if I must give up, what can I do to have the best possible chance that my guest vm isn't totally hosed?

    You patience ought probably to be in direct proportion to the date since your last backup.

Solution to this is: just wait.

However, there is a little caveat, if you want that this transition is really successfully and fast you need to temporary turn on Time Machine backup.

  • What does Time Machine backup have to do with expanding the disk for the VM?

  • It somehow interfere with backup disk operation service and vm ware disk expansion service ... Quite logical to me ... May 13, 2017 at 9:09
  • As soon as I turned off Time Machine my resize completed instantly. Aug 28, 2018 at 5:53

Same here with Fusion 8.5.8 and macOS 10.13.2. I expanded a VM from 60 to 80 GB, progress bar stayed there for 30 minutes. Then it was done, all good.
