    Restoring Information Using a Time Machine Backup
    If	you	previously	created	a	 Time	Machine	backup,	use	the	Restore	utility	to	restore	
    everything	on	your	computer	to	its	previous	state.
    Use	your	 Time	Machine	backup	only	to	restore	information	to	the	computer	that	was	
    the	source	of	the	backup. 	If	you	want	to	transfer	information	to	a	new	computer, 	use	
    Migration	Assistant.
    1  If	your	backup	is	on	a	 Time	Capsule,	make	sure	your	Mac	Pro	is	connected	to	the	same	
    Ethernet	or	 Wi-Fi	network. 	( To	connect	to	a	 Wi-Fi	network,	follow	the	instructions	on	
    page	82.)
    2  In	the	Mac	OS	X	Utilities	pane, 	select	Restore	From	Time	Machine	Backup	and	click	
    Continue.

    instructions.
    Reinstalling Mac OS X Lion Server and Apple Applications
    Under	some	circumstances, 	you	may	need	to	reinstall	Mac	OS	X	Lion	Server	and	Apple	
    applications. 	You	can	reinstall	while	keeping	your	files	and	user	settings	intact.
    Important:  The	Mac	OS	X	Utilities	application	reinstalls	and	restores	Mac	OS	X	and		
    Mac	OS	X	Lion	Server	software.
    1  Make	sure	your	Mac	Pro	is	connected	to	the	Internet	via	an	Ethernet	or	 Wi-Fi	network.	
    ( To	connect	to	a	 Wi-Fi	network,	follow	the	instructions	on	page	82.)
    2  In	the	Mac	OS	X	Utilities	pane, 	select	Reinstall	Mac	OS	X	and	click	Continue.
    3  When	you’re	asked	to	select	a	disk, 	select	your	current	Mac	OS	X	disk	(in	most	cases, 	it’s	
    the	only	one	available). 
    						
    							84Chapter 4      Problem, Meet Solution
    4 To	install	optional	software, 	click	Customize.	
    5  Click	Install.
    You	can	install	Mac	OS	X	and	Lion	Server	without	erasing	the	disk, 	which	saves	your	
    existing	files	and	settings, 	or	you	can	erase	the	disk	first, 	which	erases	all	your	data	
    and	leaves	the	computer	ready	for	you	to	reinstall	Mac	OS	X, 	Lion	Server,	and	Apple	
    applications.
    After	reinstalling	Mac	OS	X, 	you	can	then	go	to	the	Mac	App	Store	and	re-download	
    the	applications	that	came	with	your	Mac	and	other	apps	that	you	purchased	from	the	
    Mac	App	Store. 		
    Important:  Apple	recommends	that	you	back	up	the	data	on	the	disk	before	restoring	
    software. 	Apple	is	not	responsible	for	any	lost	data.
    Restoring Your Computer to Its Factory Settings
    When	you	restore	your	computer	to	its	factory	settings, 	everything	on	your	computer	
    (your	user	accounts, 	network	settings,	and	all	of	your	files	and	folders)	is	deleted. 	Before	
    you	restore, 	back	up	any	files	you	want	to	keep	by	copying	them	to	another	disk. 	
    Write	down	your	network	settings	from	Network	preferences	to	make	it	easier	to	get	
    connected	again	after	reinstalling	Mac	OS	X	Lion	Server.
    1  Make	sure	your	Mac	Pro	is	connected	to	the	Internet	via	an	Ethernet	or	 Wi-Fi	network.

    2  In	the	Mac	OS	X	Utilities	pane, 	select	Disk	Utility	and	click	Continue.
    3  Select	the	disk	in	the	list	on	the	left, 	and	then	click	the	Erase	tab.
    4  Choose	Mac	OS	Extended	(Journaled)	from	the	Format	pop-up	menu, 	type	a	name	for	
    the	disk, 	and	then	click	Erase.

    computer	may	improve	reception.
    	
    ÂMake	sure	the	side	panel	is	closed	(follow	the	instructions	starting	on	page	46)	and	
    the	PCI	port	access	covers	are	in	place	(see	 “Adding	PCI	Express	Cards”	on	page	68).	
    Antenna	reception	is	reduced	when	your	Mac	Pro	is	not	closed	properly.
    	
    ÂCheck	the	 Wi-Fi	signal	level. 	You	may	have	up	to	four	bars	in	the	 Wi-Fi	status	icon	(Z)	
    in	the	menu	bar.
    	
    ÂFor	more	information	about	 Wi-Fi,	choose	Help	>	Help	Center, 	and	then	search	
    for	 “Wi-Fi.” 	Also	see	the	instructions	that	came	with	the	wireless	device	for	more	
    information.
