In the middle of using Adobe Lightroom my Mac decided to switch off and restart. Not the first time this has happened but usually it carries on. This time however The Pegasus R8 was not showing on the desktop despite all the blue lights being on and the standby blue light being on. I shut down the Mac and the Pegasus did not shut down. I tried pressing the standby button. Nothing. I pressed and held it. Still nothing. I switched the Mac back on and tried again. No joy. I have disconnected the Pegaus and all other extrenal devices and rest the PRAM. This made no difference either.
Is it safe to pull the power on it and hope that reboots the R8 or is there another procedure I should follow?
