Meu Problema

My MacBook 13", end 2009, 250 Gb, 2 1Mb RAM, worked enormous slow after loading Yosemite. The imac 21.5" mid 2010, 500 Gb, 2 2Mb RAM, was a little bit slower after Yosemite but had open space for 2 more RAM chips.

Minha Solução

Inside the MacBook 13", end 2009 I changed the Hitachi HD 250 Gb. I put in a 1 TB Seagate SSD Hybrid HD and 2 new 4 Mb RAM chips. To do all this was really not complicated. ifixit delivered a super repair kit! First of all I studied very good the Youtube movies about the repair procedure.

To introduce the RAM chips in the imac was an easy thing. First I was a little bit worried about how strong you have to pull at the plastic bands to take out the chips. But for my case it was not really necessary to pull those out because there was open space which I filled with 2 2Mb RAM chips. Totally I have now 8 Mb RAM. The imac works now again the best.

Both make-ups were done in a short time.

Loading the datas from the old HD to the new SSD in the MacBook:

First of all I secured the datas on a LaCie back-up HD. After the make-up I tried first to reload from the old HD by using the delivered Drive Enclosure. This didn't work correctly. It showed the "mistake 254" again and again and I was not successful. So I tried with the Lacie HD. This worked the best.

Meu Conselho

The most time I lost was to find the right RAM chip product for the imac 21.5" mid 2010.

I am very lucky to have found IFIXIT in the internet. It's really great how perfect all went on with the make-up of my old Computers: especially too the email contact, the order and payment administration and delivery. I ordered at 12-30-2014 in the morning and got the devices 01-05-2015 at 10.00 am at the door in Cham Switzerland (delivery over New Year's Day and Weekend!). Thank you very much! Great!

I have now the feeling and result of a brand new MacBook. That's amazing.
