Hi together,
I finally managed to get TC started from a usb stick on a Macbook Pro. At least nearly..
For this, I used the instruction on
https://www.pyrosoft.co.uk/blog/2013/01/09/creating-a-bootable-usb-stick-from-osx/ in order to create a mbr on the stick. The further procedure described on that site concerning the usage of unetbootin didn't work. Instead I installed the bootable usb stick as I always did (via a small tool for win) for getting it worked on a PC.
But what's happening now (and without any success whatever I tried to solve this) is, that after loading TC in the boot manager, TC doesn't load any extension but only its kernel. That leads not to the GUI (startx doesn't work, too) but to the shell.
I also tried the boot option for slower machines setting the waitusb on 10 sec. The result is the same as without that option: the screen telling that tc kernel is loading appears, finishing with the line that TC extensions are being loaded with that moving cursor behind.
Interestingly the shell doesn't allow to mount the usb stick ("no such device"); sda1 - sda3 are shown in folder but neither access nor mounting from /dev to /mnt is possible.
The stick which is used has a write-protection switch which I always activate when using live systems.
It seems as the second folder ("cde") on the stick (the first is "boot" with core.gz, vmlinuz and syslinux etc.) with xvesa and co. in it is ignored. I also renamed it to "tce" without success. Also, I copied Xorg in that folder (not in its subfolder "optional" where xvesa can be found).
I've got a rather old TC version (the standard one with 12 MB) from mid 2013 that has always worked fine on my old 32 bit (single core) PC as well as on a 64 bit (multi-core) PC.
Can you imagine where that problem comes from and how I could solve it? - In case you need more information please let me know.
