Important:  Instructions	that	refer	to	modems	do	not	apply	to	LAN	users. 	LAN	users	
might	have	hubs, 	switches,	routers,	or	connection	pods	that	DSL	and	cable	modem	
users	do	not	have. 	LAN	users	should	contact	their	network	administrator	rather	than	
an	ISP.
PPPoE Connections 
If	you	are	unable	to	connect	to	your	Internet	service	provider	using	PPPoE	(Point	to	
Point	Protocol	over	Ethernet), 	make	sure	you	have	entered	the	correct	information	in	
Network	preferences. 	
To check your Network preference settings:
1  Choose	Apple	()	>	System	Preferences.
2  Click	Network.
3  Click	Add	(+)	at	the	bottom	of	the	network	connection	services	list, 	and	choose	PPPoE	
from	the	Interface	pop-up	menu. 	
4  Choose	an	Interface	for	the	PPPoE	service	from	the	Ethernet	pop-up	menu. 	Choose	
Ethernet	if	you	are	connecting	to	a	wired	network	or	 Wi-Fi	if	you	are	connecting	to		
a	wireless	network.
5  Click	Create.
6  Enter	the	information	you	received	from	your	service	provider, 	such	as	account	name,	
password, 	and	the	PPPoE	service	name	(if	your	service	provider	requires	it). 	
7  Click	Apply	to	make	the	settings	active.

Network Connections
Make	sure	the	Ethernet	cable	is	plugged	into	your	MacBook	Pro	and	into	the	network. 	
Check	the	cables	and	power	supplies	to	your	Ethernet	hubs	and	routers.
If	you	have	two	or	more	computers	attempting	to	share	an	Internet	connection, 	be	
sure	that	your	network	is	set	up	properly. 	You	need	to	know	whether	your	ISP	provides	
only	one	IP	address	or	multiple	IP	addresses, 	one	for	each	computer.
If	only	one	IP	address	is	provided, 	then	you	must	have	a	router	capable	of	sharing		
the	connection, 	also	known	as	network	address	translation	(NAT )	or	 “IP	masquerading.”	
For	setup	information, 	check	the	documentation	provided	with	your	router	or		
ask	the	person	who	set	up	your	network. 	The	AirPort	base	station	can	be	used	to		
share	one	IP	address	among	multiple	computers. 	For	information	about	using	an	
AirPort	base	station, 	check	Help	Center	or	go	to	the	AirPort	Support	website	at		
www.apple.com/support/airport.
If	you	can’t	resolve	the	issue	using	these	steps, 	contact	your	ISP	or	network	
administrator.
Problems with Wi-Fi Communication
If you have trouble using Wi-Fi communication:
	
ÂMake	sure	the	computer	or	network	you	are	trying	to	connect	to	is	running	and	has	a	
wireless	access	point.
	
ÂMake	sure	you	have	properly	configured	the	software	according	to	the	instructions	
that	came	with	your	base	station	or	access	point.

ÂMake	sure	your	MacBook	Pro	is	within	range	of	the	other	computer	or	the	network’s	
access	point. 	Nearby	electronic	devices	or	metal	structures	can	interfere	with	wireless	
communication	and	reduce	this	range. 	Repositioning	or	rotating	the	computer	might	
improve	reception.
	
ÂCheck	the	 Wi-Fi	(Z)	status	icon	in	the	menu	bar. 	Up	to	four	bars	appear,	indicating	
signal	strength. 	If	you	don’t	see	the	bars, 	try	changing	your	location.
	
ÂGet	help	online	by	choosing	Help	>	Help	Center, 	and	then	searching	for	“wi-fi.”		
Also	see	the	instructions	that	came	with	the	wireless	device	for	more	information.
Keeping Your Software Up to Date
You	can	connect	to	the	Internet	and	automatically	download	and	install	the	latest	free	
software	versions, 	drivers,	and	other	enhancements	from	Apple. 	
When	you’re	connected	to	the	Internet, 	Software	Update	checks	to	see	if	any	updates	
are	available	for	your	computer. 	You	can	set	your	MacBook	Pro	to	check	for	updates	
periodically, 	and	then	you	can	download	and	install	updated	software.
To check for updated software:
1  Choose	Apple	()	>	System	Preferences.
2  Click	the	Software	Update	icon	and	follow	the	onscreen	instructions.
	
ÂFor	more	information, 	search	for	“Software	Update” 	in	Help	Center.	
	
ÂFor	the	latest	information	about	Mac	OS	X, 	go	to	www.apple.com/macosx.

To	operate	the	computer	safely	and	reduce	the	possibility	of	heat-related	injuries, 	
follow	these	guidelines:
	
ÂSet	up	your	MacBook	Pro	on	a	stable	work	surface	that	allows	for	adequate	air	
circulation	under	and	around	the	computer. 	
	
ÂDo	not	operate	your	MacBook	Pro	on	a	pillow, 	blanket,	or	other	soft	material, 	because	
the	material	can	block	the	airflow	vents. 	
	
ÂNever	place	anything	over	the	keyboard	when	operating	your	MacBook	Pro. 	
	
ÂDo	not	push	objects	into	the	ventilation	openings.

your	lap	and	place	it	on	a	stable	work	surface.
Water and wet locations		Keep	your	MacBook	Pro	away	from	sources	of	liquid, 	such	as	
drinks, 	washbasins, 	bathtubs,	shower	stalls, 	and	so	on.	Protect	your	MacBook	Pro	from	
dampness	or	wet	weather, 	such	as	rain,	snow,	and	fog.
