Installing Additional Memory
Your	computer	has	two	memory	slots	that	you	access	by	removing	the	bottom	
case.	Your	MacBook	Pro	comes	with	a	minimum	of	4	gigabytes	(GB)	of	1333	MHz	
Double	Data	Rate	(DDR3)	Synchronous	Dynamic	Random-Access	Memory	(SDRAM)	
installed. 	Each	memory	slot	can	accept	an	SDRAM	module	that	meets	the	following	
specifications:
	
ÂDouble	Data	Rate	Small	Outline	Dual	Inline	Memory	Module	(DDR3)	format
	
Â30	mm	(1.18	inches)
	
Â204-pin
	
Â2	GB	or	4	GB
	
ÂPC3-10600S	DDR3	1333	MHz	 Type	RAM
You	can	add	two	4	GB	memory	modules	for	a	maximum	of	8	GB	of	memory. 	For		
best	performance, 	fill	both	memory	slots	and	install	an	identical	memory	module		
in	each	slot.
To install memory in your MacBook Pro: 
1  Follow	steps	1	and	2	beginning	on	page	37	to	remove	the	bottom	case.
Important:  When	you	remove	the	bottom	case, 	you	expose	sensitive	internal	
components, 	which	can	be	affected	by	static	electricity.
2  Before	touching	the	memory	assembly, 	discharge	any	static	electricity	from	your	body	
by	touching	a	metal	surface	inside	the	computer.

from	the	memory	card	slot. 	
The	memory	pops	up	at	an	angle. 	Before	removing	it,	make	sure	you	see	the	half-circle	
notches. 	If	you	don’t, 	try	pushing	the	levers	outward	again.

4 Hold	the	memory	module	by	its	notches	and	remove	it	from	the	slot. 	
5  Remove	the	other	memory	module.
Important:  Hold	the	memory	modules	by	their	edges, 	and	do	not	touch	the	gold	
connectors.
6  Insert	the	new	memory	module	in	the	slot:
a Align	the	notch	on	the	gold	edge	of	the	module	with	the	notch	in	the	lower		
memory	slot.
b  Tilt	the	card	and	push	the	memory	into	the	slot.
c  Use	two	fingers	with	firm, 	even	pressure	to	push	down	on	the	memory	module. 		
You	should	hear	a	click	when	the	memory	is	inserted	correctly.
d  Repeat	to	install	an	additional	memory	module	in	the	top	slot. 	Press	down	on	the	
module	to	make	sure	it	is	level.

Making Sure Your MacBook Pro Recognizes the New Memory
After	installing	additional	memory	in	your	MacBook	Pro, 	check	whether	the	computer	
recognizes	the	new	memory. 	
To check the computer’s memory:
1  Start	up	your	MacBook	Pro.
2  When	you	see	the	Mac	OS	X	desktop, 	choose	Apple	()	from	the	menu	bar	and	then	
choose	About	 This	Mac.
For	a	detailed	breakdown	of	the	memory	installed	in	your	computer, 	open	System	
Information	by	clicking	More	Info, 	and	then	click	Memory.
If 	your 	MacBook 	Pro 	doesn’t 	recognize 	the 	memory 	or 	doesn’t 	start 	up 	correctly, 		
confirm 	that 	the 	memory 	you 	installed 	is 	compatible 	with 	your 	MacBook 	Pro 	and 	that	
it’s 	installed 	correctly.

An Ounce of Prevention
If	you	have	a	problem	with	your	computer	or	software, 	having	kept	up-to-date		
Time	Machine	backups	ensures	that	your	data	won’t	be	lost. 	If	you	make	regular		
Time	Machine	backups, 	you	can	restore	your	software	and	all	your	data	to	exactly		
the	way	it	was	at	the	time	of	the	backup. 	Even	serious	issues	are	of	less	concern		
when	you	safeguard	your	information	with	 Time	Machine.
