I have a mid-2009 13.3” MacBookPro5,5 with Intel Core 2 Duo 2.26 GHz processor and 2*1GB DDR 3 1066MHz of memory. I have bought the mac a 2*2GB Crucial DDR3 1066MHz CT2KIT25664BC1067 memory and a 96GB Kington V+100 SATAII SSD in order to give a boost midway through it’s life. As a result I am working out if I should take advantage and upgrade to Lion and take full advantage of the OSX 10.7, iCloud and iOS5 integrations however I have been hearing there are some teething issues with Lion, such as the flash videos not playing correctly in Safari. Also I am hearing that the pre Intel iSeries (i3/5/7) processors are struggling Lion’s increased processing requirements and I ask the members of this forum that it might be better to stay with Snow Leopard (OSX 10.6.8)? Has anyone had experience of using Lion on with the same generation MacBook Pro? How was it? Did you have any issues? Would you have any recommendations it either way? Objective and impartial advice only please.
