RAM related issue...
I have an iMac 21.5" mid2010 and a macbook pro 13" early2011 both with preinstalled 2g + 2g ram
Can i do this:
1) Buy 4gb + 4 gb more ram
2)insert this into my MBP and take out the preinstalled 2gb + 2gb
3) insert the 2gb + 2gb taken out from my MBP to iMac's extra 2 slots
4) so i'll get 4gb + 4gb ram in MBP and 2g + 2g + 2g + 2g on iMac. thus making it 8gb in both the macs
...😕
iMac, OS X Yosemite (10.10.2)
