fixed : “Convert to APFS” option greyed out in Disk Utility (in Catalina Patcher)

Question :

I am trying to install macOS 10.15 Catalina on an unsupported MacBook Pro that I have lying around. I downloaded the Catalina Patcher from and watched the instruction video. I am following the instruction video to the letter and everything seemed to work okay so far, but now I have to reformat my internal HD to APFS, using Disk Utility, I can’t do so because the “Convert to APFS” is greyed out…

What am I doing wrong ?


Answer :

Nothing maybe… is your MacBook (Pro/Air) already running macOS 10.13 High_Sierra ?

If your Mac is running macOS 10.13 High_Sierra, your disk format may already be APFS !

To check, in Disk Utility, select your internal disk in the list on the left and if in the middle, under the disk’s name, it says “APFS Volume • APFS”, your disk is already formatted as APFS… so in that case you can skip the ‘APFS formatting’ step and proceed with the next step of the instruction video…

If it doesn’t say “APFS Volume • APFS”, try the options lined out here :


That’s it !

fixed : a (relatively) quick fix for Photoshop not wanting to install on Case-sensitive formatted HD

Question :

Today, I wanted to install Photoshop on my Mac, but the installer refused because I have my Mac HD formatted in “MacOS Extended (Journaled, Case-sensitive)” format.

How can I easily fix this ?

Answer :

Photoshop (both Photoshop Elements and Photoshop CS) can not be installed on a Mac that has a “MacOS Extended (Journaled, Case-sensitive)” formatted internal HD. It just can’t. There is only one route to fixing this that will help here : you need to reformat your HD.

So here’s the quickest way to reformatting and restoring your Mac’s internal HD without loosing data :

– make a Time Machine backup of your HD
– plug an OSX 10.7 installer (USB-stick or DVDrom) into your Mac

Note : if you don’t have an OSX-installer, here are directions on making one :

– make sure you have a new DVD-writable or a completely empty 4GB USB-stick

– download Lion Disk Maker and follow the instructions that come with it :

– restart while pressing the ALT-button
– choose the OSX EFI volume to boot from
– open Disk Utility
– click on the Erase tab
– select your internal HD, and “MacOS Extended (Journaled)”
[ and NOT “MacOS Extended (Case-sensitive, Journaled)” !!! ]
– click Erase (a new name for the HD is not important)
– when the erase (reformat) is finished, exit Disk Utility and go to “restore from Time Machine backup”
– make sure your Mac is connected to the Time Machine disk by a cable connection (either Ethernet/UTP, USB or FireWire)
– select the volume called Data and continue
– select the subvolume that has your previous HD’s name
– click Restore and wait
(restoring can take up to one hour)
– afterwards restart your Mac normally
– do a quick check to see if things work properly
– put in the Adobe Photoshop Elements installer DVDrom and follow the installer instructions
– done !
