Known issues
As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu MATE 15.10. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:
In Virtualbox, the installer currently has a bug where after the installation is complete, the installation medium will eject, but you will be unable to press ENTER to reboot. Powering off and back on should boot you into your installed system. This is being tracked in bug 1447038
The amd64 (Intel x86 64bit) images specifically targeted at Apple hardware (amd64+mac) are no longer produced. Most Apple computers are now capable of booting the amd64 image directly using the EFI (not legacy) boot method so long as their firmware is up to date. If for some reason your hardware doesn't boot properly using the amd64 image, make sure you don't have a pending EFI update and if that still doesn't work, then patch the 64-bit ISO using the software in 1298894 (tested working on Macbook 2,1). Alternatively, simply use the i386 (32bit) image instead.
Due to changes in syslinux, it is not currently possible to use usb-creator from 14.04 and earlier releases to write USB images for 15.04; we believe that it is also not possible to use usb-creator from a 15.04 system to write USB images for earlier releases. For now the workaround is to use a matching release of Ubuntu to write the images, but we intend to issue updates soon to work around this incompatibility. 1325801
Marco 1.10 is unstable on some Integrated Graphics Processors from Intel, this is being tracked in 1495313. If you are affected, these are the work arounds:
Use Compiz as your window manager, which can be enabled via MATE Tweak
Install metacity and use it as your window manager. Metacity can be enabled via MATE Tweak
