    Gaming apps freezes for few seconds , then resumes by itself or crashes sometimes ,after upgrading to iOS 8.3 on iphone 6

    Update: my phone's connecting to the WiFi again. I don't know what did the trick. I did nothing since reinstalling the software. It hadn't worked then, it is now. I tried connecting to my dad's phone's hotspot( he uses a Moto G), and it worked. I then tried connecting to the WiFi at a friend's house, and when I came back home, my phone was able to connect to my WiFi! Is it of any significance that my friend's router doesn't require a password? My issue has been resolved( for now; I hope I'm not counting my chickens before they've hatched). For anyone facing a similar issue, I suggest you try everything I did:
    1. Turn your router off for a minimum of 30 seconds, turn it back on and try connecting.
    2. Click on the WiFi network you are connected to, scroll to the bottom, tap "Renew Lease".
    3. Do a soft and hard reset.
    4. Reset network settings.
    5. Back your data up, erase all content from settings menu, restore from backup.
    6. Reinstall your software( put it in recovery mode).
    I am not sure which of the above worked for me. Make sure you try everything. If none of the above works, take it to a genius bar or an authorised service provider. Good luck! :)

    Hi Guys,
    I found the solution on Adobe's forums. Thanks to the adobe guys.
    I have a program "RightZoom" installed. Needed to upgrade that to the latest "Lion Compatible" version.

    Sorry, possibly you need a new hard drive or try reformating. First
    you can try something like http://www.alsoft.com/diskwarrior/  it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
    If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

  • If external monitor is placed above laptop screen, dock won't appear on external monitor

    I've just migrated from PC to Mac and I've found something that drives me crazy.  The dock won't appear on my external monitor if the external monitor is placed directly above the MacBook Air built in display.  At home. I plug in my external monitor into my MacBook Air, place my laptop on my physical desktop just below my elevated external monitor.  My MacBook Air is open and I use its keyboard and its display, but my main display is my external monitor. I configured displays to match the physical arrangement:
    Darn:  the DOCK REFUSES to appear on the "main screen"!!  This drives me crazy -- this did not happen in Windows!  The task bar obeyed my "main display" setting.
    I can get the dock to appear on the main screen if I tell Mavericks of an arrangement that suits Mavericks -- somewhat side-by-side, as follows:
    Now the dock shows up on my external monitor which I'd identified as my main screen before all these shenanigans.
    The problem with the workaround is that the mouse does not track correctly between monitors so it's not an acceptable workaround.
    Does anybody have any ideas on how to work around this for real?

    Try booting your laptop normally, and then plug in the external monitor when the computer has fully logged in (or when it's waiting at the login screen). Does the problem still happen when you do that?

  • I can't download OS5 or, rather, iTunes does download it about 450 mb and then, a few seconds after it starts processing the file, I get the message that I am timed out and am recommended to check my internet connection. I am using 3g to download it.

  • IMac freezing every 30 seconds or so

    A strange new thing has started happening with my system.. Every 30 seconds or so the system seems to freeze for a few seconds then unfreezes and is fine for a period of time. For instance if I am playing a game that is graphic intensive the play will be fine till it hits that freeze point then all displays, response etc. pause. A few seconds later everything jumps to where it should be. The same thing happens if I am typing in Word for instance. I can keep typing and the system will catch up after freezing. If I watch the Activity monitor when this happens, the CPU usage seems to drop to 0 or very low then jumps right back up. Obviously this is an issue.
    I have ran the TechTools Deluxe and it didn't find any issues.

    Hi Asstinterests, Welcome to Apple's Users Help Users Forums.
    It looks like your gaming is kicking you into Virtual Memory. More Ram would be the cure. The only puzzle is why typing in word would kick in the same problem. Try quitting extra apps and see if it goes away.

  • ITunes 7.0.2 freezes a few seconds after I open it

    Every time I open my iTunes, it works fine for about 2-3 seconds (enough time for me to go to my music library or to connect to the iTunes store) and then it completely freezes. Nothing looks different on the screen, but I can't scroll, play any music, change folders, or do anything. When I open task manager, it says iTunes is not responding.
    I uninstalled Quicktime (and then deleted the quicktime folders from "Program Folders" and "C:\Windows\system32\"), restarted my computer, turned off my security anti-virus program and then repaired iTunes, but that didn't change anything.
    No error messages come up or anything like that; it just freezes every time. Thank you for any help you can give.

    I have OS 3.1.3 and around 10 smart playlists. I used to turn off Live Updating when I'd sync my smart playlists, but when I updated to the latest OS, I left it on because I thought they had fixed it. >_<
    I can't look at my smart playlists right now because iTunes isn't recognizing my iTouch at the moment -- the iTunes and Music app problems occurred at the same time, and I was hoping that fixing the Music app problem would also fix the iTunes problem.
    ... While I was writing this response, I used MediaMonkey to +sort of+ fix the problem. My iTouch was appearing in MediaMonkey with no songs; I added a song to my iTouch using MediaMonkey, and after that the Music app worked and iTunes recognized my iTouch. Yay!
    However, I can't see most of my music library -- I only see the songs I had purchased on my iTouch. I suspect that the rest of my music is still floating around on my iTouch somewhere, though, because now I have a big chunk of memory taken up by (orange) Other data.

  • Screen blacks out after a few seconds and won't return to normal state.

    I have the 30 gig ipod photo that i got about a year and a half ago. Whenever I look at the screen to access music or anything, the screen blacks out like there's a screensaver or something and won't return back to normal. Even after I reset it, it stays normal for a few seconds and then blacks out again. The backlighting still works so it's just a bright black screen and I have function of the click wheel because it clicks everytime I move up or down. I already tried restoring it so I am all out of options. Anyone PLEASE HELP!!! Thanks
    Steve

    This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.

  • Address  Book freezes a few seconds after opening:  'non-reponsive'

    Address Book Menus show but get beach ball of death in a few seconds. Does open normally under alternate user. Status: have reloaded and updated 15.3 with auto restoration of settings and have deleted various Address Book .plists and all 'Address Book Files' all to no avail. User doesn't use Mail, but has Skype operating. Haven't checked to see if Mail opens correctly. Obviously I can't open permission. i'll need help on how to implement suggestions. Thanks in advance.

    I fixed the problem. FYI, it was a font problem. It turns out that somehow I had acquired a duplicate of Helvetica. I could tell there was a duplicate because there was a bullet to the right of the listing in FontBook.
    To fix, highlight the font (Helvetica) and go to Edit/Resolve Duplicates.
    Address Book now opens and I can access all my contacts.
    In addition, it resolved a problem I had with the computer not shutting down. AND it resolved the problem of my Mail icon in the Dock not showing the little red circle when I had unread mail.
    I am thrilled.
    Help this might help anyone else.
    Sincerely,
    Gale

  • Every time I open iPhoto (as of today) after a few seconds the coloured wheel appears and the program become unresponsive. I have tried closing my computer. I assume I have a corrupt file but at the moment I cannot access anything in the program?

    Every time I try to open Iphoto '11 (as of today) the coloured wheel appears after a few seconds and the program becomes unresponsive. I assume I have a corrupt file but I cant do anything including accessing help. I have tried closing down and restarting but it dosnt help. Any ideas please?

    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

  • Gnome-Shell 3.8 freezes a few seconds when i start an application.

    Hi!
    I've been using GnomeShell for abount 1 year now. But there is an pretty anoying thing with it. When i open (for example google-chrome) the clock stops and i cant click on anything for about 3 seconds. But not only when i start an application but also randomly when i busy with developing PHP etc. Is this an known issue? And is there a way to fix it?
    Cheers,
    Kevin

    I can confirm this issue partially. When I try to search for the application, I type a few letters (depends on the speed of typing) and Gnome freezes for a few seconds.
    Probably
    extra/tracker
    is the cause.
    Edit:
    I have removed tracker, gnome-photos, gnome-documents, but with no luck - it still lags. I did the trick with:
    top > /tmp/top
    and proceed everything again. This shown me that the problem was gnome-contacts, which went to the ~70% CPU.
    I removed it as well and everything works fine now.

  • Mouse cursor freezes a few seconds after start-up? Need help!

    Laptop: Samsung Series 9
    OS: Windows 8.1
    Problem: since booting up my computer today, my cursor will freeze about 30 seconds after boot-up. Prior to this, I'll be able to move my cursor for a few seconds as I normally would, but then I will inevitably see the blue loading circle next to the cursor
    and then my cursor will be frozen in place. I can still use my keyboard/everything else functions regularly. I decided to boot up my computer in safe mode and my cursor works fine. Clearly then, there must be some software/start-up issue? 
    I should note that I used my laptop fine yesterday night. When I booted it up today my cursor froze and I saw the restart prompt that said windows will restart on its own in 1 day to update. So I updated/restarted and the problem persists.
