Macbook hangs when unlocking only when connected to university wifi. Any suggestions?
So, when I am connected to some university's wifi, It takes longer than a minute to unlock the screen. The process goes something like this when the laptop is connected to university wifi:
1) I click to bring up the password
2) I type in the correct password and press enter
3) I wait for ~75 seconds
4) The screen unlocks
When I am connected to home wifi, or a different institution's wifi, or no wifi
1) I click to bring up the password
2) I type in the correct password and press enter
3) I wait for less than a second
4) The screen unlocks
The fact that I always wait 75 seconds (I just tested it 3 times), leads me to think it might be a timeout for something, but I'm stumped as to what the lock screen could be doing with the wifi!
Any suggestions?
This also happens for any check of my password (e.g. when I try to unlock system preferences). When it does, I am unable to use they keyboard for anything.
I also forgot to mention that my hard disk is encrypted with FileVault.

I just upgraded to Yosemite and can no longer connect to the WIFI any suggestions
I Just up upgraded to Yosemite and can no longer connect to internet - any ideas?
I have the same problem after loading OS X 10.10 Yosemite on my MacBook Pro (Late 2008). Wi-Fi (Time Capsule) connects OK, then I open Safari and it waits for a minute and then gives me a message that it can't load the page because I'm not connected to the Internet. The Wi-Fi is fine. When I run the network analysis, it shows that everything is fine up to the Internet; the dots are red after that. I have another MacBook Pro (Retina, Mid 2012) and it loaded and runs with no known problems (so far). I am writing this message on the Late 2008 MacBook Pro, so you can see that there is no problem with the Internet connection. It is a Yosemite problem. My iPhone and newer MacBook Pro connect with no problem. I loaded Yosemite TWICE, then ran the Disk Utility and fixed some disk permissions but there were no other problems identified. Restarting after reloading Yosemite and the same problem is there. Restarted after running the disk utility and fixing disk permissions and it still can't connect to the Internet. Same problem. Does anyone have an idea how this might be fixed? What's going on? Thanks for your help.

Does the iPod connect to other networks?
Does the iPod see the network?
Any error messages?
Do other devices now connect?
Did the iPod connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

How to turn off screen on Macbook Air when connected to Computer LeD monitor?
How to turn off screen on Macbook Air when connected to Led monitor screen?
The only way you can turn it off is to close the lid - so you would need an external wired or wireless keyboard and mouse/trackpad attached.

My ipod touch has stopped playing through my Sony docking station, It only plays through the i pod. It's not the docking station as my daughter's ipod works fine on it. It can synch when connected to computer. Any ideas what is wrong?
Have discovered that I had not in fact updated the ios!!
Went through the process last night and my ipod now works fine on my docking station.
Thank you very much for your advice. -
I just bought the new MacBook Air a few days ago and my Internet connection is so slow. My iPhone's connection works fine when connected to the wifi but the MacBook connects for a few seconds then drops completely. What do I do? I tried connecting it to my phone's hotspot and it works perfectly. I'm a new Mac user so I have no idea what to do. I have Comcast xfinity cable and Internet. Thanks for the help.
Your warranty includes 90 days of phone support. Contact Apple.

ITunes 11.1 hangs when connecting to iCloud. How can I download 11.0.5?
Arrrrgh! iTunes 11.1 hangs on my system Windows 7 x64 when trying to connect to iCloud. It runs fine if I start it in safe mode (I have no third party plug-ins installed).
How do I download iTunes 11.0.5???? I've been searching on the Internt for the last 1/2 hour and it looks like Apple prevents users from downloading 11.0 once 11.1 (piece of crap) is out. WHY?????????Hi,
I've been able to resolve the problem of iTunes crashing by emptying the SycServices folder - by following the steps described at the foot of this comment. I've also been able to sync my iPhone contacts with my Address Book ...but I cannot sync my Address Book with Outlook 2011 ... and thus my iPhone linking to Outlook 2011.
I'm aware that 'Sync Services' were depreciated in 10.8 and was hoping that this would be restored in full in v: 10.9.3. I understand that MicroSoft needs Sync Services to be reintroduced into the OS to enable the sync to work again for linking up with Outlook 2011 - which appear to be blank in my Sync Services preferences window as follows ....
I would be mighty grateful for any ideas/solutions on how to resolve this problem. Synching Outlook 2011 with my iPhone was so easy in the past!
Simon
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Application Support/SyncServices
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. Log out or restart the computer and empty the Trash. Test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Re: iTunes ver 11.2.1 hangs when connecting to iPhone -
I have an ipad2. When connected to my wifi at home it will not download you tube videos for easy viewing. Do I need to upgrade my connection speed? Would 3 Mbps be enought or do I need to go to 6 Mbps. I mainly use my ipad to view emails, browse the internet and watch you tube videos.
thanks - MichelleWelcome to Apple Support Communities.
There are a number of factors in the 'speed' equation. Any or all of them can affect the 'observed' speed of your connection.
1. Are you in a neighborhood full of WiFi routers (and thus, lots of WiFi interference)? I can 'see' at least 22 other WiFi routers from my living room!
2. What is the maximum connect speed and band and bandwidth available from your wireless router. Is it 802.11n or the older 802.11a/b/g? 300Mbits or 150Mbits? 2.4Ghz or 5Ghz or both? Does your router measure (QoS) Quality of Service and can it change 'channels' automatically?
3. What is the observed strength of your wireless connection? Are you getting at least 80% signal when connected? Are there other people in your family also using significant bandwidth at the same time (Netflix, streaming video, streaming audio, game systems)
4. What is the "advertised" speed of your current ISP connection?
5. What is the measured throughput of your current setup. Go to speedtest.net or use the free speedtest.net app available in the App Store. Try several times, from different locations in your home, and at different times of day and night.
I have AT&T DSL advertised at 3Mbit/sec down and 512Kbit/sec up. My Speedtest.net measured throughput is about 2.4 Mbit/sec downstream and upstream is about 0.4Mbit/sec. I'm using a Motorola Netopia 2210-2 DSL modem. I have no problem viewing YouTube videos and other mobile video content on the iPad 2. I'm connected wirelessly to a D-Link DIR-655 Gigabit router rated at 150Mbps at 2.4Ghz (only) with 802.11 b/g/n enabled. The interior of my home is within a range of 30-50 feet from the router and no more than 1 wall. It is a single level concrete slab foundation of about 1500 sq. ft. with cathedral ceilings. I have successfully streamed ESPN3.com on my MacBook at the same time my son was streaming another ESPN3.com game on his MacBook Pro. I've streamed YouTube videos while my son was watching a NetFlix movie on his Wii game system. He's also successfully used Skype for extended 'teleconferences.' None of my devices are connected to HDMI on a large screen TV. 95% of the time, I can do iChat video without any signal breakup to my son (who is at a college with a Gigabit (1000Mbit) wired connection!). 5% of the time the connection drops. We haven't tried FaceTime (designed for mobile connections to be much less bandwidth-intensive, from what I understand) simply because we both have iChat on our computers.
So for me, a 3Mbit DSL connection is absolutely adequate, given all the other parameters mentioned. As the car manufacturers say, "Your mileage may vary."

I was able to transfer my music from my old PC to my new one and connect to the newest version of ITunes but my playlists from my old PC do not appear on my new PC when I open ITunes. Any suggestions?
Copy everything from your old computer, or your backup copy of your old computer, to your new one.

When connecting to my wifi I get ! When looking for networks
When connecting to my wifi I get ! When looking for networks
IWhen you see an exclamation point in the Wi-Fi menu, from the menu bar, select
▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test. -

Outgoing mail isn't sent when connected to some wifi networks
Although my outgoing mail goes out just fine on cellular networks, and on my home wifi, outgoing mail isn't sent when connected to some wifi networks.
I use the apple outgoing mail server.
What is unusual however is that my outgoing mail address is not from a standard domain. I have my own.
Could it involve an spr record?Do you have a wireless network at home and Is the email account provided by your internet service provider associated with your wireless network?
Most, if not all internet service providers block the use of SMTP servers that are outside of their network or not provided by the ISP being used for your internet connection at the time unless the SMTP server is authenticated. The same applies when connected to the internet via the cellular network. Recieving is not a problem regardless the ISP being used for your internet connection at the time.
If the email account is provided by your ISP, most ISPs do not have an authenticated SMTP sever for the email account they provide.
Both my email accounts have an authenticated SMTP server and I've never had a problem sending with either account regardless the ISP associated with a wi-fi network I'm connected to at the time or when connected to AT&T's cellular network - for 2+ years aporoaching 3 years this July. -
When I have my handsfree plugged in, the sms-tone and incoming-call ringtone is only played in my earpluggs. Any suggestions anyone?
I experience the same problem and it's extremely annoying. Have you found a solution yet?
Of course one might want to keep the earphones plugged in most of the time (if this is the way you prefer to answer you calls + talk on the phone) even if you're not using the phone/earphones. The ringtone does come through to to the speaker when someone calls… yet the sms signal DOES NOT and only plays in the earphones.
This means that the earphones must be unplugged after every call and then plugged in again before every call in order not to miss any sms:es! (Talk about unsafe driving e.g.!)
It would seem to be such an obvious setting/option to include in the iPhones settings. Why has Apple has completely missed this!? .... or is there a solution?
I have searched the internet but haven't found a solution?
