disk utility – Unable to shrink MacOS partition – Sonoma 14.4.1 (23E224)

After a lot looking out and attempting all kinds, I bit the bullet, backed up my recordsdata and used the restoration/bios function of my 2019 15″ intel MBP to reinstall macOS – throughout this course of I used to be in a position to choose the scale of the disk for the brand new macOS set up and create a partition to be used with linux in a twin boot…

This concerned holding command+r throughout boot after which choosing to delete/erase my HD, making a important 800gb partition for macOS which then left 200gb free – after which choosing to reinstall macOS on the 800gb partition.

Unrelated – however doing all this was a little bit of a waste of time, I used to be attempting to check the T2 variations of Arch and Ubuntu 24.04 to see if they might run properly on my 2019 MBP {hardware}…

Though I had a free 200gb partition, T2 Arch nonetheless wished to reformat my total disk…

So I switched to T2 model of Ubuntu 24.04.

This put in efficiently on the 200gb partition however overwrote the macOS efi partition so now my Mac boots into linux by default – if I maintain choice earlier than boot, I can choose macOS as wanted… and I’m certain I can reset/right this with out to a lot ache.

In Ubuntu I couldn’t get the wi-fi driver to work and I additionally discovered that bluetooth was a little bit hit or miss with my mouse and keyboard… aside from that Ubuntu appeared to run fairly properly…

Having stated all this, it appears reinstalling macOS has improved the efficiency of my system barely and I’ll now be capable to re-size my partition if wanted in future…

Further: I additionally tried to resize the partition after putting in the newest macOS Sonoma 14.5 replace however this did not not assist with the resizing challenge so I made a decision to only go together with the reinstalling of macOS…

All in all, placing a contemporary set up of maOS was most likely factor as I had simply saved upgrading the unique 2019 macOS with out reinstalling the OS every time a brand new model got here out…
