    Hi all,

    just wondering if anyone has tried this. Waiting for New iMac to arrive and some software I use is not compatible with El Capitan yet.

    Thanks

    not possible, it will not work. Yosemite has no support for Skylake. USB ports will not work a full speed.

    This is a problem for me and others too. My printer and scanner will have to be replaced, altho OK for Yosemite, no good for El Cap.

    Yeah thanks, thought as much.

    For me it would mean installing Windows 7 on bootcamp then. Just need to buy a copy now

    Same Problem for me.
    Apples update cycle is becoming ridiculous.
    All the third parties aren´t able to follow track, so more and more stuff gets unnecessary obsolete.

    How about installing the relevant KEXT extensions from Yosemite (USB in this case)?

    possible?

    Possible but it may cause more problems then you're trying to address.

    How old is your printer and scanner? I have a laser printer that's 8 years old and is still supported by Brother. When you say these don't work has the manufacturer definitively said they will not supply drivers for them or are they just late?

    There is 3rd party software if there is something unique about your printer and scanner that you want to keep them. Check out http://gimp-print.sourceforge.net/MacOSX.php and http://www.silverfast.com Gimp print is freeware, silverfast (scanner) and it's companion PrinTao8 is traditional for pay.

    If your printer and scanner are just run of the milll varieties then these are very inexpensive these days and an upgrade is worth the price of admission. Good laser and scanners are in the $100-200 range. If you only need a "good" scanner Brother AIO laser/scanners/copiers/fax are $250.
