Shock! Horror! Yesterday, I realised that – and I’ll blame this squarely on work – I’d slipped back into using OSX in that unconscious, it’s-what-I’m-used-to way. So I tried booting into Ubuntu on my macbook to find that it just refused to boot up. The boot choice led to a black screen. Then I realised that I’d updated OpenCore Legacy Patcher recently (it’s an old macbook running Sonoma) and somehow it had screwed up the EFI bootloader during the update. I spent the evening scratching my head and trying to find explanations for what should be a straightforward fix. Turns out that what was missing was the ext4_64.efi driver and an entry in the config.plist pointing to the driver. (To make things more irritating, I’m convinced I did this when I first installed Ubuntu.) What it’s made me realise is that I really do need to get hold of a dedicated linux laptop.
