Ram issue since 10.4.6 update

I notice that after the 10.4.6 update the memory usage is different, having now almost everythin inactive and very little free. Before the update i have the larger part allways free.I have 2gig and i know it is not that important but still find weird.

Generally Apple posts most of what has changed in the release notes between updates. If you recall what version you were at prior to your update, you may want to read all of the release notes for the updates in between the version you upgraded from and the version you upgraded to.
Generally speaking, there is always something for your RAM to be doing -- if its not needed for program execution, it can be used for caching purposes. Sitting idle is probably not the most efficient use of your RAM.

  • Major iPad 3 WiFi connection issues since 5.1.1 update

    Prior to the 5.1.1 update (which ironically was supposed to fix wifi issues), my iPad 3 worked great.  Since the update it has been a complete disaster. 
    Even though it always shows a strong wifi connection, certain apps seem to have no connection while others work fine.  Safari usually works ok, although sometimes pictures won't show up - just a small box in the corner.  Facebook app always seems to have issues as does Pandora.  The biggest problem is the App Store or iTunes which say it cannot connect even though Safari works fine at the same time.  Ive tried reconnecting, rebooting, and I even bought a new router since I thought maybe my old one was causing the problem.
    Is Apple fessing up to this issue?  I have to believe it is a software/firmware issue since before the update everthing worked fine.

    Can't connect to the iTunes Store

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • PDF Preview Issues since 10.6.5 Update

    I've noted posts of similar PDF issues since the 10.6.5 update, though not exactly like mine. Since the update some PDF's are not rendering properly.
    Specifically no text shows up (though the headers / graphics, underlines and text boxes were there). I forwarded the email to iMac running 10.6.4, and no issues, it reads fine. My iPhone also reads it fine.
    Anyone having similar issue? Trying to understand whether this is some over-zealous security thing in the new update (note: I trust source of the PDF in question), since other PDF's can be read with no problems.
    Thanks,
    Kevin

    Thanks LD. Did the repair, reinstall, repair as suggested however the PDF's in question still do not show the written (font) part of the doc. So I investigated further asking the authors how they created their PDF and both were on a cheap (free?) version of Nitro.
    So, I think I'll put this issue as solved, since I'm guessing that 10.6.5 just won't play nicely with all PDF creators until the 3rd parties do their own updates.

  • Call connection issues since iOS 8.1 update

    Ever since the iOS 8 update on mine & wife's iPhones (5s & 5c) we have had nothing but issues with receiving various phone calls, even with the newer updates with bif fixes etc the problem persists. We have tried to remedy it by turning off the 4g option as we heard this was a solution but no change. Same with wifi also. It's not a network problem as we have a very good signal. Like I said we have had this problem from the moment iOS 8 arrived, we're now on iOS 8.1, still no change. Does anyone have a clue to fix this?

    Same issue here, both my boyfriend and I updated our iPads and iPhones to 8.1, now FT crashes constantly, when we try to FT from iPhone to iPad we just get "connecting" and nothing happens. If we do iPhone wifi to iPhone cellular we get same "connecting" problem. If we do iPhone to iPhone and enable cellular it connects. When we do iPad wifi to iPad wifi it connects but then crashes constantly. I have tried ft with others who have not done the updates and it works fine Using the same Internet connection. We have switched to skype to video chat and it works just fine, so it can't be an Internet issue.

  • Adobe Pro 9 Issues since 6/17/11 Update

    Adobe Pro 9 presents the following issues since I updated it on 6/17/11:
    Before the update, I could select multiple pages in the Pages thumbnail view by using my Shift or Ctrl key while selecting the thumbnails with my mouse, this no longer happens since the update. When I click either my Shift or Ctrl and try to click on the thumbnails, nothing happens! and,
    Before the update whenever I did a Find for something on a converted document, that which met my search criteria would be highlighted on each page. This, too, is no longer the case since the update.
    I REALLY wish I could go back to Adobe Pro 9 before the 6/17/11 update because the update has been more of a downgrade.

    Obviously there were no answers to this issue. In reading this was an ongoing issue that has yet to be resolved within Adobe. It appears to go back several years with numerous threads on very similar issues. Does Adobe just not care about this that anyone can see. As a small business the constant upgrading is very inefficient cost wise.

  • ICal/Google sync issues since iOS 8.2 update

    Since the update to iOS 8.2 a few days ago, iCal on my iPhone 5s is not syncing with my Google Calendar.  I have already reset the 2 step verification on my Google calendar permissions, checked to make sure events are in the Google calendar and not in the iPhone calendar, and checked settings to make sure the Google calendar is selected.  The only thing I have not tried (because I'm worried that changes I made prior to realizing thisi was an issue would be lost) is deleting my Google account from the iPhone and reconnecting.  Is that really my only remaining option?  I'm stumped. 

    I'm facing the same issue on iOS 8.2 iPhone6. iCal is not syncing on the iPhone. It does, however, sync from Yosemite to iCloud.com.

  • Connection and Keyboard Issues (since 10.5.5 update?)

    Not quite the connection issues others are having, once Airport is connected, it stays connected. The issue is with initial connection. When I wake the Macbook up from sleep, I can't click to load anything on the internet/ in email for almost a full minute. If I do, or if mail tries checking for new email, whatever is attempting to load continues to attempt doing so for about 30 seconds or so, when it then tells me that I am not connected to the internet. Airport, however connects to the wifi just as quickly as ever (or, at least, it says it's connected). I just started noticing this issue the other day, around the time I updated to 10.5.5, so I can only assume it's from the update. I have not had any connection issues before this (the Macbook is about 3 months old).
    The other issue I've noticed does not happen consistently. Once in a while, when I press the button to decrease screen brightness, the brightness decreases completely and the screen turns black. The other day, I opened the computer up, and the screen was "stuck" black. I couldn't get the brightness to increase. While trying to tap keys to "wake it up," at one point I heard a ding, as if there was an alert that I needed to click OK on or something. I ended up giving up and holding the power button down to shut down and reboot, and haven't had the problem again since.
    I've searched the forums to see if others are having these problems, but all I can find is problems with frequent connection drops, and, like I said, I'm not have that issue.

    Help?
    This is very frustrating.

  • Strange Typing issue since latest OS X update

    I cannot type in any finder window since updating to 10.5.7
    I can copy and paste, but I can't type. I can type on the desktop and in spotlight, but once I open the spotlight window (view all results) or open a finder window, the keyboard keys stop functioning.
    Is anyone else experiencing this? What could be causing this. I've tried a wired white Pro Apple Keyboard (I use the wireless white Pro Apple Keyboard) but it didn't fix the issue either.

    Hi Sandy:
    Try trashing the preference file (com.apple.finder.plist) and restarting.

  • IMAP gmail issues since software 2.2 update!!

    I recently (yesterday) downloaded 2.2 for iPhone. Since then I have had gmail email issues on the phone. Today I tried the following things - all with the same result (cannot connect using SSL, account verification failed, IMAP server errors):
    Have restarted phone (several times).
    Have erased mail account and entered again (tried with google button, used "other" and tried both IMAP and POP) (several times each)
    Have checked my gmail account for issues (both enabled for IMAP and POP)
    Can someone help me? Not much of a point of having an update which is supposed to help the "push" issues, when you can't access email at all. Does anyone know if Google is having issues?
    Thanks!

    In case anyone viewing was wondering, I think their must've been an outage at gmail this afternoon for a while. The exact same settings now work for IMAP. I'm gonna cross my fingers that it doesn't keep happening

  • Weird Firewire Issue since 10.5.6 update

    Hey guys!
    I'm a musician so I use an audio interface (Presonus FP10) to record my stuff. It's a firewire interface and it used to work perfectly fine.
    However, since the 10.5.6 update there seems to be something wrong with my firewire port and I haven't found anything on the web that fits my problem.
    If I plug in my interface into the firewire port, it doesn't work. It neither goes on nor is recognized by the OS.
    Although, once I plug in my ethernet cable for internet access, it works fine.
    Problem with this is that in my music room there is no possibiliy of pluging an ethernet cable.
    I hope somebody can tell me what to do in order to get this fixed, whether this problem is caused by Leopard or by my interface.
    Thanks,
    Mark

    That was my first guess, too. See, that's what makes it all so weird:
    I have the device plugged in with no other cable. Nothing happens. I have the ethernet cable plugged in without anything connected to that. Nothing happens. I then plug it into an internet router ét voilá! It works...Could it maybe be a lack of electricity coming from a damaged AC-Unit connected to the device?
    But then again, it all worked fine up to the 10.5.6 update. Did the apple people do something to the firewire driver?I hear the new Macbooks come without Firewire...

  • Sound issues since 10.5.2 update

    Since the update I've lost all sound in Xp running in Parallels sound is also gone from Mac mail & trash.
    Other areas maybe too.
    Volume control stuck and can't be moved also.
    Anyway I've discovered if I create another administrator account and log in sound and volume control work. (not sure about Parallels though but I think it should)
    So it looks like to me that the update has damaged the account somehow. Is that possible.
    Is there a way to transfer all my programs and files to this new account without any reinstalling?
    Would I have to install all my programs again?
    Is this the correct way to solve this problem?
    New to Mac's (one week) so please keep it simple.

  • Bluetooth Issues since most recent Security Update

    I just updated my Macbook Pro and my wife's MacBook Air, and all of the sudden, our Bluetooth Apple Keyboard and Magic Trackpads are undiscoverable.  I just spoke to a friend in San Fransisco who said the exact same thing is happening with his computer since he installed the latest updates.
    Anyone else having this problem?

    Fixed the problem from advise from another topic. I ran repair permissions and now everything I think is back to normal. I have so few problems I always forget about "repair permissions" Thanks for the advice!

  • IPhone4 Bluetooth issues since 4.2.1 update

    Hi,
    since iOS 4.2.1 on iPhone4, phone doesn't always connect to bluetooth handsfree carkit as in the past. Every few connections (< 10), I have to reset phone in order to be connected back to the carkit.
    The connectivity problem occurs both with Renault Carminat CNC and BMW multimedia systems.
    Anyone having a workaround for this?
    Thanks,
    Michel

    The problem already occurred with iOS4.2GM 8C134, not in iOS4.1
    There is no log accessible via Xcode devices organizer

  • Anyone else having issues with location services since the 7.1 update? Ever since I updated i've been seeing the location services on my status bar at all times.

    Anyone else having issues with location services since the 7.1 update? Ever since I updated i’ve been seeing the location services icon on my status bar at all times. I noticed that google was the app that was using it a lot, but after I turned the feature off for google my phone started using the “traffic”, “frequent locations” and “cell network search”. When I turn the feature off for all of those things it’s no longer a problem. So just wondering if anyone else is having this issue or if anyone has a solution?

    The "solution" is probably to increase your knowledge.  You've done good things.  Perhaps this article will educate you a bit more about location services.
    Basically, they can be very useful, but can cause a lot of iPhone use.  A major example is "Remind me to ... when I leave home."
