Hi all,
I am trying to install Sequoia on an iMac A1311 (Late 2009) via an OLP 2.2.0 USB installer. The installer has been created successfully using the correct model and a fresh downloaded OS.
On the iMac, the HD has been replaced with an SSD, and the RAM upgraded. It has a wired USB mouse and keyboard. On boot, I can get to the Recovery options, and can select the Installer option using the keyboard only (the SSD was formatted also using keyboard only).
For the installation, I can get as far as 'Select Disk for Installation' but cannot use Tab and Space to switch and select on screen options. Disks available are Untitled (the SSD) and the USB installer (greyed out).
Doing some research I found some others had used Voiceover to get past this step. However, it seems this does not work with Sequoia as although activating Voiceover works fine (Command + F5) switching the focus to the disks (Control + Option + Shift + Arrows) does not do anything.
I'm stumped. I have also tried using other keyboards and mice, and plugging in the mouse into the keyboard like a USB hub to get it to work - but whatever I do I can only get keyboard functionality and no mouse - so I cannot select the Installation destination disk. Please Help! Many thanks.......
