How come my mac doesn't remember my preferred wireless network?

I have to pick it out of a list every time. I have deleted the network and recreated it, but not luck. Is there a preference file I need to trash and then restart my computer? This started happening out of nowhere.

Thanks to eveyone that replied. None of the suggestions fixed my problem, but they look like they fixed at least one other person's, kudos to all of you. I ultimately "fixed" the problem by reformatting the drive and reinstalling snow leopard. I did NOT elect to transfer my Settings when I used Migration Assistant to move the stuff from my backup. Extreme? Yep, but it worked. Warning if you have Norton Antivirus 11, if you do what I did, NAV gets screwed up and you will likely need to email NAV support for a newer version.

How to be Sure my iMac sees my Preferred Wireless Network Each Bootup

I am still setting up my new iMac and deciding what to keep and what not to keep from my previous primary computer (G4 iMac running Tiger). The old G4 is still hardwired to my D-Link wireless router (DIR 615) and my new 21.5 inch is connecting wirelessly. The connection is basically really good and the iMac picked it up right away upon initial setup. I will eventually move the new iMac into the old G4's place and wire it up.
Here's my occasional difficulty. Sometimes, when my old G4 is off and I boot my new iMac I get a message saying something like my preferred network cannot be found. Usually I am given an opportuity to then log into said preferred network and it works fine. I, as best I can tell, have it designated the preferred (and so far the only) network in Network preferences. It seems like when my old G4 is already booted up that this is not a problem and my new iMac immediately connects.
As an aside, a household iPod touch and an Xbox 360 have no problem connecting with my D-Link regardless of whether the G4 is booted or not. The status of the G4 may just be a red herring and I may have just overlooked something in the network setup on my new iMac, although there really was no setup to speak of, it just worked from the start.
Thanks for any ideas.
Regards,
Steve M.

It says my 3.01 is current and no updates are available. It does actually give me this message.
Since my router is basically working OK now, I guess I won't pursue updating the firmware anymore than doing this check. Thanks.

How come my mac isnt showing my external hard drive after installing os x maverick? and how to i fix that??

how come my mac isnt showing my external hard drive after installing os x maverick? and how to i fix that??

How do you mean it isn't showing the external drive? If you mean on the desktop, click Finder on the menu bar, Preferences, General and check the boxes for Show these items on the desktop - make sure hard drives is checked.
If you mean it is not showing in Finder or Disk Utility, make sure it is turned on, reboot and see if that mounts it so it shows up.

What exactly is your 'mass USB device', and how is it formatted? When you connect it to your MBA, does it show up on the desktop?

How come my mac's battery charges fast and drains fast as well?, How come my mac's battery charges fast and drains fast as well?

I would like to know why my Macbook Air 13 IN. (The one before the newest one that just came out) loses battery so fast and also charges so fast? Literally, it takes about 2 hours for my mac to charge, which I love, but then when it is not plugged into the charger, it's battery life runs out in about 2 hours as well. The only changes I have made to my copmuter in the last month (when this problem began) was upgrading to Mavericks and playing games. First, I updated to OSX Mavericks (huge mistake on my part for various reasons). Secondarily, I began to play graphic intensive games on my mac; games like Team Fortress 2 on Steam. I began playing them very often. Now, I know, you all probably think that this is obviouslty the reason the battery drains so fast, and I get that, but how come it charges really fast too? It hasn't always done this, however. It used to take hours to charge and it would therefore last MUCH longer. So I basically have two questions; How come my mac's battery drains AND CHARGES so fast, and what can I do to restore its charging abilities back to their original state?

Yes, even playing the graphics intense STEAM games would have no accounting for ultra-fast charge times.
Since your Mac is short-charging your Air and there is wrong information being fed that a full charge has occurred when it in fact hasnt (as per your indications) then:
perform a SMC reset, and if same, you'll need to make an appt. with your Apple store for full diagnostics of possible IO board or battery circuitry issue.
SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Mac NOT automatically connecting to preferred wifi network

Hi,
I am facing a problem with OS X 10.9.1 (Mavericks) wifi connection.
I use a Time Capsule as a base station and 13" Macbook Air (2012). The base station is connected to the internet through a PPOE connection.
Here are the details.
Since upgrading to OS X 10.9.1, my Mac automatically connects to preferred wifi network ONLY WHEN the wifi is available at start up or when the Mac wakes up from sleep, but NOT OTHERWISE.
Before the upgrade, the Mac automatically connected to the preferred wifi network not just at start up, but whenever the wifi became available.
In other words, after the upgrade, if I boot up the Time Capsule base station and the Mac simultaneously, the Mac scans for the base station wifi network (this is configured as the top preferred wifi network) at start up, but since the base staion is still booting up, the Mac doesn't find the wifi.
But once the base station has booted up and wifi is available, the Mac no longer bothers to join it. At this point, the Mac is also not able to do Time Machine backups to the Time Capsule because it is not able to locate the Time capsule disk over the wifi.
This situation remains (i.e., the Mac being not connected to the wifi) unless I do ONE of the following:
1. I manually select the preferred wifi network using the wifi icon at the top of the screen; OR
2. I put the Mac to sleep (by closing the cover) and then wake it up. On wake up, it connects automatically to the preferred wifi network; OR
3. I turn of the wifi (using the wifi icon on the top) and turn it back on, at which point, the Mac automatically connects to the preferred wifi network.
I have tried everything possible including contacting Apple support, but so far the issue is unresolved.
Appreciate any help you can provide.

I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
Open DNS and write down your DNS server. Delete it and re-enter it manually.
This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

I think the best you can do is use the System Information application (Utilities Folder), looking in the wireless section.

Photoshop Elements Editor 11 Mac doesn't remember open files

I just installed PSE 11 on my Mac (OS X 10.8.2). My previous version (PSE 6) would re-open all files that had been open when I quit the app last time, but this version always opens with a blank screen. I can't find any preference in PSE to affect this, and the overall Mac setting is set properly. How can I get PSE to remember what files I was working on?

The File->Open Recent files show recent files list. If you are talking about files automatically reopens in PSE then there is an option on Mac under Settings->general which says "Restore..."

How come messenger info doesn't sync?

In the Address Book; the name, address, email, phone number, picture, all sync. But how come the AIM screen name doesn't sync? It shows up in the Address Book on my Mac, but not in the Contacts on my Touch.

It would appear that Apple, for whatever reason, have decided not to include fields for instant messenger names in the iPod touch Contacts application.
Even if you enter a new Contact on the iPod touch, there is no provision for those fields.
Try sending Feedback to Apple about this:

How come my Mac only shares 51 out of 500 photos from my iCloud account?

My Mac doesn't recognize my iCloud account with the exception of 51 out of 500+ photos? How can I connect everything to iCloud. I have gone into my iCloud settings and that doesn't seem to work.

If the contents that accumulated on the new phone while the spell of Alzheimer went away is not indispensable, perhaps the quickest way would be to reset and wipe the phone then reregister it to the original iCloud account so you would get all your old content/apps/etc. back.

How to get Mac and PC to print via wireless

I have a G4 20" iMac that is hardwired to high speed cable internet. I also have PC that I need to print from but, is not hard wired to anything. In fact, it is imperative that the PC not be hooked to the internet. I am buying a HP 1320 laser and I would like to print from both computers. How can I set up wireless printing to the HP 1320 so both my iMac and PC can print while keeping the PC totally free from the internet?

you have a few options, but you should provide more information.
1. do both your imac and pc (is it a desktop or laptop?) have wireless capability already?
2. is your imac connected through a router (wireless or wired), or directly to the cable modem?
given you have wireless capability in both imac and pc, you have a few options.
1. If you just want to use a wireless print server (wps) create ad-hoc connection between your imac and wps and between your pc and wps.
2. if you are using a wireless router, you can configure the client IP Filters to bloc internet access for the pc. Or, you can keep the wired internet connection to the imac and use the wireless router to control your wireless network.
i think your best option is #1, though. just ensure you do not have internet sharing enabled on your imac.

Tethering: Mac doesn't recognize iPhone as a network interface

Hi all,
I've been trying to get my iPhone to work with tethering, but for some reason my Mac won't recognize it as a network interface.
Funnily enough, if I plug it into my friends new MacBook 2GHz Aluminum MacBook it does work. Just not on my ol' plastic MacBook...
Any ideas what I'm doing wrong?

Yes, I had. But I kept stopping one step too early, namely clicking on the Apply button after manually adding the new internet connection, as the DNS records etc. weren't automatically filled.
Which was stupid, of course.
But I just followed all the steps again, and am now SORTED!
thanks.

How to connect an Ethernet laser printer to a wireless network?

hi, I have three computers on an Airport Xpress wireless network. I have an (non-USB) HP Laserjet 4100 that has a network card (10/100tx HP Jetdirect 600N). How do I connect this printer to my network? Can I wire it directly to one of my computers using a standard ethernet cable? or do I have to set up a hub? Any insight most appreciated!

There's another way to do it...
I have a Linksys wireless router for my home network (and internet) and have my HP LaserJet 4000 hooked up to it, and all my computers can print to it. However, it does require a Windows computer for set-up, because HP makes the set-up utility for Windows only. (I set it up with my Intel Mac running Win)
Follow these instructions:

Hope it helps.
