Mountain Lion, internet network question

Since downloading & installing OS X Mountain Lion, my WiFi network times out when I put my computer to sleep after using the internet. How can I manipulate the WiFi settings so that I don't have to choose my own network and enter my password each time?

I really appreciate any responses or opinions. I have found the Apple Support communities to be amazingly helpful so far.
Thank you again!

  • Upgrading to  Mountain Lion Pre Install Questions

    HI:
      I will be installing Mountain Lion Next week.
    I have read through many of the turotrials and quired most of the following  I still have a few questions.
      I have some concerns in particular regarding the contents of my mail boxes and mail.
    I have backed up unto an external harddrive using time machine. When I click on the mail app I can't access it and see if the contents are there. I just get a window showing the specs.
      From what I have read all my documents applications and system info are backed up.
    1} Will the contents of Mail Inbox and personal Mail Boxes be either on the external drive or in Mail itself after I upgrade?
    2} Will I need to up grade iWork  and other Mac programs after the upgrade?
    3} Does time machines automatic backup, back up everything or do I need to do a manual back up for some thing?
    4} Will I need to load new drivers for external devices such as my printer and mouse?
    5} Will I need to reload third party soft ware such as Adobe Elements 9?
    6} Will my bookmarks and homepage be saved in Safari?
    Lot's of Questions, I have limited broad band width and will need to do most of this from a friends and internet cafes so I need to be prepared time wise and finanancialy as some things will have to be done at home and are going to push me into the next teir of my flex plan, possibly past the final teir.
    Any and all advice will be appreciated.

    1. You have a backup of your mailboxes in Time Machine that you can restore, but Mail won't modify your mailboxes during the upgrade. The first time you open Mail after the upgrade, it will upgrade your mailboxes to be able to work with that new version.
    2. If you upgrade from Snow Leopard, you should know that there's a newer iWork '09 version for Lion and Mountain Lion that make it compatible with iCloud, so you will have to install updates for iWork at least. Respecting to other apps, you have to consult it with the developer.
    3. Time Machine makes a backup of everything in your OS X partition, and it makes automatic, hourly backups. If you want, you can also make a clone with Carbon Copy Cloner or Disk Utility's Restore feature in another external disk. The advantage is that you can start the Mac from it.
    4. Theoretically, Snow Leopard, Lion and Mountain Lion use the same printer drivers. Respecting to the mouse, if you are using a third-party mouse, you have to consult with the developer if your mouse is compatible with OS X Mountain Lion.
    5. Third-party apps won't be deleted unless they aren't compatible. See > http://www.roaringapps.com
    After downloading OS X Mountain Lion, I recommend you to make a bootable copy with Lion Diskmaker, so you won't have to download OS X Mountain Lion each time you have to reinstall OS X Mountain Lion

  • Purchase Mountain Lion for network installation

    Hi I've been having freezing/lockup issues with my iMac (mid 2007).  It is currently running Lion 10.7.5
    I had it into the Genius bar, they checked the hardware and said it was good, the issue was coming from 'one of my files' on my backup.  (I had restored from a Time Machine backup). 
    So, I am trying to run a network install to do a 'clean' install of Mountain Lion, but it says I haven't purchased it yet and won't let me proceed with the install.   Seems like a simple question, but how do I purchase Mountain Lion so I can do a network install without being on my iMac? 
    If I can do a network install, then I can troubleshoot the backup files and have a known fresh starting point if I need to reimage.
    Any thoughts or pointers appreciated.

    I will try that again, and post the results. Suffice it to say I have done quite a bit of troubleshooting and tried various things.  At this point I would just like to be able to get back to a clean image and then troubleshoot which files on my backup may be contributing to the issue.   If anyone else has ideas on how to purchase ML without using my iMAC please let me know - I can get it to run for about 5 minutes (when I restore from a TM backup) but then it just freezes or generates Kernel errors.   Genius bar told me all the hardware checked out.

  • Can't login after Mountain Lion upgrade (Network accounts are unavailable)

    I performed a Mountain Lion upgrade on a 2011 MBP running Lion this weekend. The Mac may have been set up to connect to an AD server with my user account, but I thought I had disabled that months ago... aparently not. I performed the upgrade at home not on the corporate network.
    On first bootup after the Mountain Lion upgrade I'm stuck at the login screen unable to login with my local account or the admin account. I get the "red dot" next to the username field with the "Network accounts are unavailable" pop up. I'm plugged in to the ethernet network at work now... no luck.
    I tried booting into the repair disk and repairing disk permissions. Still no luck.
    Any ideas? I'd happily do a fresh install but I need to get a handful of files off the machine first.

    No worries with the basic questions... it's important to cover all the bases. Thanks so much for the input.
    - I'm trying to log in with the same username I would use to ssh in... so yes.
    - I don't know if the account was a mobile account. The Mac was given to me configured about a year ago, configured to be on the domain. I since have used it on and off many networks without considering it was set up to be on a domain.
    - Never had a problem logging into the machine before the mountain lion install, although to be honest it was very very rarely ever rebooted.
    - I've plugged it into ethernet and let it sit for quite some time. It's still telling me Network accounts are unavailable and I'm unable to login with my personal or admin account.

  • Mountain lion upgrade network failure

    Hi,
    I´ve done the upgrade 10.6.8 to 10.8 on a MacPro (2010) from USB-stick. Everything works fine, but no networks after restart! When I klick the networks-icon in system pane, I only get the spinner and system pane crashes. Update 10.8.1 installed, the same...
    Before the upgrade my mac works stable with 10.6.8 and 3 vlans on ethernet1.

  • Mountain lion software update questions

    I have a couple of questions about the software update process in Mountain Lion.
    I know that the old software update has been ditched and now updates will be routed through the app store instead, but could anyone tell me where the list of installed updates is located? I ask because under System Preferences > Software Update the default check boxes suggest that updates will be downloaded and installed automatically, which is all very well but I would like some kind of notification that they are being installed/have been installed or I will worry that I am missing them.
    Secondly as another user reports here: https://discussions.apple.com/message/19080258 the 'Last check' message remains frozen on the day I installed Mountain Lion, i.e. it says that the last check was yesterday (July 28th) even though I did a manual check today (29th).
    Thank you for your time

    In the past,  I have taken certain larger upgrades from apple at non-peak hours (magically everything was installed quickly) other times I have taken large upgrades from apple at peak hours ( I took forever and I questioned what is going on) this could be the issue.  "server load" or your ISP (internet service provider)
    * peak hours (when a lot of people are off work down loading the newest os or applications)

  • Mountain Lion slow network

    We recently started using Mountain Lion at work, installed it fresh on a formatted server and we're having some terrible problems with the network. We have reinstalled twice and the problem persists;
    Its running terribly slow on the local network. Downloading a small (~2MB) PDF is taking around 30 - 60 seconds. Internet is running fine, downloading goes at a realistic speed, on both the server and the machines we are trying to connect locally.
    The server is connected via ethernet, the other machines we have connected via ethernet and WiFi with no difference. Everything is running slow, Wiki Server, Profile Manager, WebDAV, etc.. Initially we thought it was due to the server memory, as it was running around 90% usage, but after upgrading it we're still having the same issues. A lion server in the exact same situation works fine.
    Any advice would be appreciated.

  • Mountain Lion, home network and choosing a new printer...

    We recently upgraded to Mountain Lion. We have multiple iMacs and use an AirPort Extreme. We also have iPhones and iPads. I am upgrading my printer, but am unsure how to make sure the printer will be compatible and will work on our network. This has been an issue in the past and networking is not my strongest skill. What do I need to look for to ensure my investment is not a waste of money?
    I am looking at the HP LaserJet Pro 200 Color M276mw, HP LaserJet Pro300 color MFP 375nw but am still open to other options if it suits our needs and will work with our network.

    Eric, I just found that document a little while ago. It was what influenced me to choose the 200 series, since it was on the list.
    I believe you are correct Gerald. I believe I am now planning on buying, but I want to ensure I know how to install it so everything will work properly. I am not sure if that will require a direct network connection, wireless or something else. I don't like to get something, know it *should* work and fail to be able to accomplish that. LOL
    I called the folks at HP. Luckily for me the Mac tech support section is closed on the weekends and only works Monday - Friday. *sigh*

  • Mountain Lion Internet only available through Chrome

    I have a 17-inch, early 2009 MacBook Pro. 2.66 GHz Intel Core 2 Duo.
    After installing Mountain Lion everything was working fine for a couple of days, then suddenly I could no longer access the internet through Safari. At the same time Mail stopped connecting to the server. The last email I was able to receive was at 10.00am GMT on Friday 27th July. Tried opening the Software Update/App Store window. It does not connect either. The pop-up window states "App Store cannot verify a secure connection with the App Store" When I click "connect anyway" the open window flashes, strobe like, between black and white.
    My Wi-Fi connection is active and I can access the internet using Google Chrome. In fact I'm typing this on Chrome on the same Mac. iTunes Store connects, Dashboard connects as does DropBox.
    Can anyone help?

    I have almost exactly the same problem - but using ethernet, so it's not specific to wifi.
    Got a brand spankin' new i7 imac today, took it out of the box, upgraded to Mountain Lion. Internet connectivity seems ok otherwise, but attempting to load the app store does exactly what dnd stated. Likewise, (although I hope there's none yet), software update forces the app store to launch, then gets the warning error, then the app store screen flickers like crazy between "cannot connect to the app store" and a black screen filling the app store window.

  • Want to upgrade to Mountain Lion, but CS6 questions about Auto-Save need answers...

    Hi,
    I'm on Mountain Lion for all my "non-critical" work, but I'm still running the latest Snow Leopard on my main desktop machine, running CS6 Design & Web Premium. I've avoided the switch primarily because of the auto-save feature that Apple placed into ML. I haven't found a satisfactory answer anywhere on the web to this basic question...is auto-save a problem, as Apple implements it, with CS6 and working on images?
    In particular: 1. I work on very larger files, 4GB+ in size regularly, and I don't wan't the peformance hits associated with constant saving, 2. I make changes to images, downsizing them, croping, color corrections, etc. so that I can make jpg proofs for clients or myself. These are more "intermediary" images and not intended to be saved. I don't want to downsample an image, flatten it to creat a jpg for proof and have it overwrite the original image layered, high res by mistake. Does this happen with photoshop, or does Adobe avoid the auto-save that Apple uses?
    I have all the latest iOS gadgets and it's becoming quite cumbersome managing multiple sets of iCloud info, etc. without being on ML. I'd like to make the switch, but at the cost of losing work, etc. Can someone with experience on ML & CS6 give me any input in the matter? And, does this also apply to all the other Adobe apps in CS6? I'm constantly making minor changes and edits that I usually "undo" out of and don't want saved.
    Thanks.
    Craig

    So, in other words, photoshops behavior works the same, using save as..., etc. as it did under Snow Leopard? I should expect the auto-save behavior that occurs in apps like iPhone, etc., where i can actually lose the original because of the constant backups, etc.?
    Thanks.

  • Mountain Lion / EFI Firmware Question

    Hello All,
    I have a straightforward question. I have a Mid-2009 15" 2.53ghz MacBook Pro, that currently has Lion installed on it. Last year, I wanted to upgrade the hard drive, encountered the EFI Firmware 1.7 issue, downgraded it to 1.6, and everything works fine now.
    My Question: I want to upgrade to Mountain Lion, but dont want my hard drive issue to reemerge: Does EFI 1.7 automatically install as part of the Mountain Lion install? Can I upgrade OS X without disabling my machine's abililty to have a hard drive?
    Thank you!
    Jeremy.

    I really appreciate any responses or opinions. I have found the Apple Support communities to be amazingly helpful so far.
    Thank you again!

  • Mountain Lion - Power Nap Question!

    I understand the new ' Power Nap' application in Mountain Lion lets you download all the mails and other updates even Mac is in sleep mode.
    Do I have to be connected to Internet for automatic downloads? They say Mac adapter only needs to be connected but do I need to be online to receive automatic updates?
    Sanket.

    You would always need to have an internet connection, and be connected to it, to recieve software updates. That is where the updates come from, IE the internet. So without one where do you think it would get the updates from, Thin air?

  • Mountain Lion-Time Machine Questions

    Hi all,
    Recently I bought a new Macbook Pro and upgraded to Mountain Lion. This laptop comes with one internal hard drive ~ 750GB. I have two questions regarding Time Machine:
    1. Can I partition my disk into two partitions so I can use one partition for Time Machine backups?
    2. Can the partition for Time Machine backups have less space than the other one?
    I know the disavantages to do so, but I just want to know if it is possible. Does Time Machine allow it?

    Post in the OS X Mountain Lion community in the "Time Machine" section.

  • Mountain lion loses network drive

    Seems like most (but not every) time I wake my iMac from sleep, it loses my network drives.  Any idea why?
    Details:
    24" iMac (not sure why that will make a difference, but whatever)
    Mountain Lion
    Using AFP to connect to my Western Digital MyBook World Edition II.  Please don't say it's the NAS, my two other computers in the house (Windows) don't have any problem w/ the nas.

    My Mac Pro will not stay connected to my Windows box.
    When I open the Network in the Finder it is blank for a very long time, and there are no options for me to refresh or see any kind of status. Just blank.
    Randomly, it seems, the PC will appear in the network list and I can use it.
    However, if I begin a file transfer to it I have to stay at the computer to monitor it because the connection gets lost when I am not there. Perhaps it is the sleep issue mentioned by the OP.
    The PC is wired; the Mac Pro is WiFi.
    Mac Pro: 10.8.2
    PC: Windows XP Pro SP3, fully updated.
    Maybe someone at Apple will read these posts and figure it out.

  • Mountain lion server network accounts are not mounting network home directory, rather its creating a blank local directory

    I have set up a scratch mountain lion server with open directory.  copied over old user account directories and added my users that match the directory ids.  Currently if a networked user logs into a networked computer, instead of mounting the network home directory, its creating a local home directory.  suggestions?
    thanks,
    Dave

    Additional info: it appears that certificates are not working either: setting up ical: "the certificate for this server was signed by an unknown certifying authority."...
