Can't install due to size of Mac OS Catalinas startup volume?

Sebrob

Hi! I'm trying to install the Una Corda plugin, which requires 43 GB on my startup volume. However, I'm on Mac OS Catalina 10.15.7 and I just realized that the startup volume "Macintosh HD" is read-only by default, and I only have 37 GB free. On my "Macintosh HD - data" I've got plenty of room (These two partitions are apparently created when upgrading to Catalina from High Sierra.) I'm stuck – any ideas how to get around this?

Hi! Actually, when erasing a lot of old files from my "Macintosh HD - data" it seemed like the read-only startup partition adjusted itself to use some of that free space, so I managed to install it after all after a day or so.

Give this a read, you may be able to enlarge the startup volume.

disclaimer: I do not own a Mac this is just suggested reading, and if you have any hesitation, you may want to consult a professional.

with that said, I have done this on Windows with success after a drive replacement (capacity upgrade) when the system restore created the system partition based on the size of the old hard drive… will admit I never crossed my fingers so hard before.🤪

Hey @Ryan_NI any suggestions for Sebrob on how to go about erasing and repartitioning a device? 🤔
