iMac supplies have already been dwindling and now customers who’ve recently ordered an iMac have received notice from Apple that their iMac purchase will be ‘delayed’ until May 2nd. That matches with what 9to5 Mac’s source has been telling them: “to expect new iMacs the week of May 2nd as Apple will officially stop shipping iMacs to resellers this week (week of April 25th)”. Previous reports have pegged this upcoming iMac update to include Thunderbolt and Sandy Bridge processors. [9to5Mac]
