  1. I had a problem with a Disk space while upgrading to 11 Beta. Installer alert the message about 16Gb required, I had 15Gb, upgrade package is ~3Gb.

    The solution was selecting the Mojave startup disk in Settings. Upgraded successfully.

  2. iMac, 32gb Memory, 2tb Fusion Drive, six external drives – Thanks for these tips. Clearing the cache is a good idea, regardless of the situation and will be doing that. My experience was not warm and fuzzy. The update had already downloaded automatically for me, and then I got a flag asking me to install. I had shut everything down (VM’s, apps, etc.) and proceeded to do the update. Once the status bar was up, there was an indication that it would take 17 minutes. I usually stay and watch, but this time, decided to get up and get something from the kitchen. When I returned what I felt was only ten minutes, the screen was completely black, but it was backlighted so I knew the system was still on but I didn’t know what was happening. I hit the keyboard to try to unlock the screen in case that was what happened, but nothing. Five minutes later it was still stuck like that. I wanted to turn the unit off and back on, but waited patiently and finally, it did the reboot and when it came back up, it indicated that it would take 58 minutes. I got up and left and returned couple hours later and logged in. That’s when I got the notice that my Paragon NTFS trial had expired, but opening my Windows 10 VM and Mint VM was horribly slow. I also kept hearing the hard drive pounding away and making noises I hadn’t heard it make before… like it was “scraping the platter”. Finally, everything calmed down. I shut down my VM’s (they were so slow) and clicked on the Paragon flag to buy the license and after putting in the license code, rebooted and when it came back, two drives that were NTFS were mounted so I can read/write to them easily. My apps were beginning to work faster but there is still some lag. It’s as though the Mac is reorganizing files in the background for the time being. I plugged in my GoPro and was unable to have anything from the mac import the files as I had been doing prior to Mojave and feel it is either Paragon NTFS conflicting or Mojave. I will dl the GoPro Quik app and see if I can transfer the videos that way. I left my Mac up and locked the screen this morning and walked away from it. I will visit with it tonight to resolve any other issues. The night mode was a bit hard on the eyes initially, but I like it. I am looking forward to the other new features. I am sure that there will be software updates and maybe one from Parallels! Again, thanks for the suggestions for fixes thus far!
