Welcome to Apple Support Communities.
First, use Finder to navigate to Applications/Utilities/Disk Utility.app and Repair Permissions on your hard drive, likely called Macintosh HD.
Safari is the app that is crashing, and you are on version 5.1.1
Try Software Update to download and install the available Safari version 5.1.5 update for OS X 10.6.8

My Airport connection drops whenever the Mac sleeps or reboots

My iBook on the same network doesn't do this.
I guess it's a settingI'venot got right, rather than a fault as such.
Any ideas?
Thanks
iMac Dual Core Mac OS X (10.4.8)

See if you can find a solution in KB 304482, Mac OS X 10.4.8: AirPort does not auto-connect to existing networks after restart or wake from sleep.

10.5.3 - Erratic Airport connection since update on Mac Mini G4

Updated to 10.5.3 a couple of days ago. First it took ages to install and the system stalled on "writing installing script". Had to take a deep breath and restart.
All was fine with wireless until yesterday when all of a sudden it stopped working. Airport reception bars went from perfect reception to 1 bar. Modem not even blinking when I try to load a page and iPhone working perfectly over wireless, so it's not the modem. Error messages are erratic, telling me that I'm not connected to the internet. Trying to turn on and off Airport works erratically. It brings back reception completely for a minute of so, then down again. I sometimes get a "connection timeout" or an "incorrect application" or something like that.
Back to the old ethernet cable then, until Apple fixes the issue. Has anyone any idea? I also repaired permissions, no change. PRAM reset maybe?

Here are some screenshots:

They are in Swedish but you should be able to understand anyway. My brother does not even have Leopard installed so I couldn't compare it as easily but what I found there was no difference. Everything seems to be okay but it just wont work.
I also found that I can't use the Apple Updater anymore because it says that I am not connected to the internet.
Also when I did the network diagnostics it ended with saying that I should restart any units I might have, and I did that and then it told me if there were any more units I could restart and I said no and then it just said that it could not solve the problem.

Mac desktop and Airport Connection

I have problem on My Mac desktop. I can't connect to my airport. my other devices had no problem with the airport connection. It shows full bar on my wifi bar but when I started to browse it tells me not connected to the Internet. I've tried resetting everything but no luck for me. Please help. Thanx!

What specifically have you tried resetting? If you are seeing and connecting to your network then that's a big first step. I would try first to see if it's a settings issue. The easiest way to do this is to create a new network location and see if the issue persists. Go to System Preferences -> Network. Select the box next to the word "locations" at the top and select "edit locations." Hit the plus symbol and name the location whatever you want (I use "test" in these situations). Make sure it's selected and hit "done" and then Apply in the bottom right of the preferences page. Give it about 30 seconds and then try to browse again. If you're successful, it was a settings issue. You can now do one of two things: find the individual setting that was causing the issue in the other location, or just use the new location you've already created. You'll probably opt for the latter, which is what I would recommend. Very, very few users have a need for a particular location setting. If you're still having a problem then it may be more complicated to resolve. I would try it on another network (at a friend's house, or at Starbucks) to make sure it's not network related. Just because your machine is the only one not working doesn't exclude the network as the root of the issue. If you have problems there, I would consult your local Apple Store or Apple Certified repair facility as it may take some deeper troubleshooting to resolve.

Connecting Logitech Z5500 to Mac Mini or to Airport?

All,
I have this cable on order (http://www.amazon.com/dp/B0002JFN1A/ref=pe_385040_30332190_TE_M3T1_ST1_dp_1) to connect my Logitech Z-5500 to my system.
Should I connect it to my Mac Mini, or to my Airport Time Capsule?
Airport: I can stream media from other devices
Mini: Avoid any lag for audio and video with FaceTime, etc.?
Maybe 6 of one, half dozen of another, but thought I'd ask.
Thanks!

ok, my problem is solved ... I was able to get the display up by unplugging the hdmi cable from the mac mini, then letting it boot up, then plugging the cable back in ... finally could see the desktop, then reset my display settings to get rid of underscanning - which I had set up the day before so I could see my top menu bar - then set my tv's aspect adjustment to HD Size 2 (which had the same effect as underscanning ... and now I get the display up when start my mac mini ... however, I do notice some fine granularity in my display now (when white windows are opened for example), but I'll deal with that later if it's a real problem ... took hours of research to figure this out ... phew ...

MAC MINI- Airport Connection cutting out regularly

MAC MINI- 10.4.11 1.5GHz intel core solo
My mac (above) keeps losing airport connection (to my BT homehub router-which is newish)- Has been running fine for years-changed my router-was still running fine for a few weeks AND NOW....keeps cutting out wireless signal for no reason. I have other macs/comps on same signal (nearer router also!) which are unaffected-only mac mini is... I have tried everything I can think of and been on forums etc all day...
Cuts out-won't recognise my router- then after a restart it sometimes comes back on-sometimes just comes back on itself after an hour or so also.... When its on, the signal gradually loses strength till it gets to zero-then disconnects and won't recognise any wireless devices (it usually lists a few that are in my building)....SO- router is OK as other comps are fine- it must be mac mini fault- have had no software updates recently either-so really don't know what to do next! help!

Hi,
thanks for your reply-I have tried every channel possible (before posting my first post)- but like I say -it connects fine at first (sometimes-especially if comp has been shut down overnight)-then after about 15-30 mins the bars start dropping and then it goes and won't come back on... I know it is not the router as my other mac (which is further away from router and also is a much older computer) has never had any problems like this before and doesn't have any while the mini is disconnecting..
I have tried everything I can think of and have spent hours and hours reading through other similar posts- but can't find anything that works....
If the mini macs have a weak antenna then why has it been ok in connecting since I bought it (was one of the first mini's to come out) ? Do you think it gets weaker with age? Why is it ok for a bit then disconnects,then is ok, then is not etc etc ??
Thanks for your help anyway-any other suggestions you may have would be greatly appreciated as I am about to throw it out the window!!cheers.

HT3546 Although I am connected to the internet via Airport the internet connection does not stay on and comes with a "time-out" message. The airport connection is still on however. I have recently bought an old Mac Book 1.1.

I have recently bought an old Mac Book after having purchased an iPhone and iPad.
The internet connection (via Airport) keeps timing out while the Airport connection is still on as confirmed by the Mac and shown on the task bar.
Any ideas?
Thank you,
Peter

Only fixed this in the last day or two . . .with this!

HT1109 Mac has no airport connection

I owed this Mac for the last four years. I recently had this problem where I can't get online anymore. I currently use airport connection to get online and had been using for the last four year. Is there anyway I can get the connection back?

Hello,
Does the Airport icon show any black bars?
Instead of joining your network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

No Airport connection with Mac Pro

I cannot get access to my (password protected) WLAN modem with my Mac Pro. I have to go via Ethernet through my Powerbook. It only works when I set the modem to require no password for Internet access, once WPA is enabled, the Mac Pro Airport connection fails even though it "sees" the network alright.
What am I to do? Any settings in the DSL modem properties perhaps?
Most grateful for answers!

That sounds like progress!
WEP / WPA and WPA2 all use a numerical (hexadecimal) key.
You give the software a readable phrase - and it turns the phrase into the number. But sometimes the same phrase becomes a different number.
Try this. Turn on WPA.
On your wireless-connected-Powerbook. Go to the network list. Click edit - and click show password.
You'll see the HEX version of the passphrase. $afbc0232...
Try THAT number on the Mac Pro.

IPhone 3Gs, Mac Pro Internet sharing via Airport connection problems

Hi, I have internet sharing turned on in my Mac Pro for the Airport connection and it works very well with laptops, but I have trouble getting my iphone 3gs to connect to it sometimes.
restarting the iphones does not help
stopping and starting the airport does not help
I can restart the Mac Pro, but that can be a pain, but does usually allow be to connect again for awhile...

I've been having the same problems as everyone else here. Trying to share internet connection from my ethernet wired iMac to my MacBook and my iPhone. Tried all the workarounds, but nothing works, or lasts very long.
Yesterday, I finally talked with AppleCare for over an hour. All their suggestions (trashing preferences, changing settings, etc.) failed, as well. The AppleCare person then put me on hold to speak to an engineer, who told her that Snow Leopard no longer supports Internet Sharing as of 10.6.1.
Not willing to accept that answer, I had them set up an appointment at the Apple Store Genius Bar for me, and after chatting with the Genius for a while, he also confirmed that Internet Sharing is no longer supported under Snow Leopard. Apparently, there were many hardware issues that the engineers decided to circumvent, and so did not include support for Internet Sharing with the internal airport in Macs. They said that the Airport it is intended to receive, not to send a signals! Yet, it worked fine, doing just that, under Tiger and Leopard! The only fix he could offer was to wipe my drive and take me back to 10.5, which I declined.
However both the guy at the Genius Bar and the lady at AppleCare inferred that Apple "may" release another update to fix this issue, if they get enough complaints and bug reports.
So, there you have it. Apple no longer officially supports Internet Sharing in Snow Leopard.

Step by step instruction on how to lock my airport connection on a mac

step by step instruction on how to lock my airport connection on a mac

Establishing and connecting to a wireless encrypted network takes two basic steps:
Administering the wireless router to configure it for a wireless security type (WEP (not recommended), WPA, or WPA2) and password.
Connecting a wireless client to the secured network by choosing the corrent security type and entering the correct password.
The "lock" symbol would only show up for a Wi-Fi network after it has been configured for security. You can't do this via System Preferences on your Mac. It would have to be done using either the AirPort Utility for Apple routers or a web-based interface for most others.

Waiting for your support ... as quick as possible ...

WiFi signals get stronger the closer the machine is to the router and the less interference/blocking of the signal like via walls with metal in them or of thick concrete.
Since the signal emanates outwards in a sphere, your supposed to place the wireless router in a central location in the building so it covers all areas.
The power of the router also has a affect, if your router is old or something not that powerful like a Airport Express, it doesn't have the ability to filter out other signals or enough punch to get through walls etc. or cover a large area as effectively.
If you buy/have a powerful router of newer make and have issues where there is metal in the walls or thick concrete, then you can buy something like OpenMesh and by using Ethernet cables from the back of the router, extend the WiFi signal into other rooms and areas past the blockage.
