"Alert: No Internet" wireless issues under Mountain Lion

Several of my and others' Macs are constantly getting alerts that they don't have internet connections through wireless as they are come out of sleep or the laptops are opened; they sometimes get the dreaded exclamation point within the Wi-Fi menu bar icon. This has happened on a 2008 24" iMac and two 2008 MacBook Pro's (one of them belonging to a friend at school); all running 10.8.2+.
And these are to different wireless routers: 2008 Airport Express, a 2003 Airport Extreme Base Station, a 2008 Airport Extreme 802.11n, and an unknown wireless router at my college (negating the possibility that it's just an issue with Apple's wireless routers).
Although I am positive this is an Apple OS bug specific to Mountain Lion, I want to see how many others are also experiencing this frustrating issue and if they are experiencing this with older versions of OS X?

I will certainly look in to this once I return from my trip, but I can already tell you that I've already performed #4 Check WiFi Connection and #5 Reinstall OS X on my MacBook Pro (due to damaging its internal hard drive a couple weeks ago when it was bumped hard while in operation) and the problem persists both before and after the reinstall.
That leaves #1 Create new location and renew the DHCP lease, #2 Reset default system preferences, and #3 Do PRAM & SMC resets. But seriously, although I can easily perform these steps, I'm not sure my friend at school could do so and it certainly doesn't bode well for Apple if some "techie" has to "fix" her computer wireless connectivity (if any of these steps actually works).
I've been noticing with every iteration of OS X, more and more annoying bugs are getting through (and not getting fixed even after repeated bug reports). I think its time for Apple to get back to basics and fix these issues and concentrate on QC instead of trying to "wow" consumers with the latest and greatest features. It tarnishes Apple's "ease of use" image when these maddening bugs get through...

Has Apple done anything to address the issue of Mountain Lion's inability to support Epson printers? I have a Stylus Photo RX620 that now is useless. I am not a computer geek so would rather not try to do an uninstall of Mt. Lion and go back to S.Leopard

Have you tried to open System Preferences, then Print & Scan and then try to Add + a printer?
I have an Epson RX580 and am using OS X 10.8.2 and it is working as a (Bonjour) printer. My Epson RX580 is plugged into my AirPort Extreme and I can print over my wireless network to the RX580. However, I do not see any Scan options with this setup.
Anyone know anything about getting the scanning portion of the RX580 to work over the network like the printing function does with my Airport Extreme? Or can I not "share" a scanner over the USB port on the Airport Extreme? I know, kind on topic/off topic - but I think it fits under OS questions better.
Thanks for your advice!

Tap to click not working properly in Mountain Lion. How do I get apple to fix this major issue with mountain lion?

The tap to click does not work with mountain lion as it did before the mountain lion install. I purchased a brand new imac in August of 2011 and got a wireless keyboard and selected the wireless trackpad instead of a mouse. The trackpad worked wonderful pre upgrade with tap to click. Now after the install of the newest beast, I have to actually press the trackpad rather than a slight tap. I have carpel tunnel and this is causing great stress upon my hand. How do I get apple to fix this major issue with mountain lion?

Perhaps, I was not clear enough.
I have an imac purchased in Aug. 2011 which came with Lion 10.6 (two uprades before mountain lion)
Recently, I just purchased a macbook pro retina with Mountain Lion
On my imac, my settings allowed me to "tap to click" everything EXCEPT the initial log in at the star up of my imac, again running Lion 10.6
On my macbook pro retina which has Mountain Lion, I set up the "tap to click" option, but notice that a "hard" click was neccessary when trying to click things. I thought this was a macbook thing (my first one) so I went and upgraded my imac to Mountain LIon, BIG MISTAKE! Now both my imac AND my macbook only have limited "tap to click" options. Before mountain lion I could "tap" to highlight and select text, tap and drag, and many other thiings that Mountain Lion has disabled.
I am truly surprised that no one has noticed this MAJOR issue.
Is there a way to uninstall this update, similar to how on a PC you can go back to a restore point.
On another note even the way PREVIEW has changed is less user friendly, there used to be icons on the bottom right corner of the screen, now I have to double tap and select the option I would like to switch between contacts and thumbnails. This is really annoying and is causing me time when reviewing files.
Just in case anyone was wondering, I did go to system preferences -> trackpad -> select tap to click
In fact almost all of the trackpad functions have been selected.

Since upgrading to Mavericks, I can no longer connect to my Bose Sounddock 10 via Bluetooth. It was fine under Mountain Lion

Pairing my Bose Sounddock 10 to my Macbook Pro (early 2011) via Bluetooth was fine under Mountain Lion. After installing Mavericks, connection failed. I deleted the Sounddock & attempted to pair it again. I get an occasional 'flash' in the 'Devices' list, but no pairing occurs.
I have no issue pairing the Sounddock to my iPad running iOS 7.0.3.
Has Bluetooth been changed for Mavericks?
Is anyone else experiencing similar issues?

I actually have the same problem, since I upgraded to Mavericks my MacBook Pro can't seem to find the Bose sounddock 10. Has anyone found a solution to this.
It still works with the iPhone 5
Thank you

Safari slow under Mountain Lion

A friendly enquiry to the Apple Expert Community
After I have upgraded my LION configuraiton with the latest MOUNTAIN LION Release, Safari has become very slow in loading web pages. I am connected to a highly performing Internet DSL Link (VDSL 20kbit's DL / 2kBit's UL).
Under LION I had no problems in this area. Also I must mention; when using FIrfox under Mountain Lion (ML), the Internet and Web Page Loading Process is very fast!
What have I done for test purposes:
1) I deactivated all iCould services to see whether it would improve - no change - still slow
2) I Did a clean ML Installation with no software etc on it - from scratch - all patches loaded etc. - Safari STILL SLUGGISH !
Assumption:
There is a bug or new feature within ML, possibly the new combined URL and Search Bar feature (searching ahead, etc) which slows down the load of Web Pages... ?
Anyhow,
The results of my short tests give me a strong indication (proof) of, the slowness of Safari 6 under ML is not caused by mal user handling or buggy software installed, but an initial insufficiency of the first release of ML
Question:
Does anybody have already found a slution to the described problem?
many thanks for some feedback

Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the page that opens.
Click the column headed Kind in the list of keychain items to arrange the list by kind. Look for certificates that are expired or invalid. Delete any you find.

Why is Safari running so slow under Mountain Lion?

Why is Safari running so slow under Mountain Lion?

I have other mac's on my home network that are still running Snow Leopard and the are performing well. I wanted to use the iCloud so I upgraded and instantly started experiencing the slow down, to the point of ridiculousness. Other function are mixed some normal speed, others a day on the beach with the spinning ball. Firefox is at full speed, good thought, haven't checked Chrome yet.
Last night and hooked into a projection unit that adjusted my screen resolution for a presentation and after the event my Mac reset back to the normal settings and Safari launched and is running normal speeds so far. In the past there have been issues with performance speeds and certain resolutions, has anyone had similar luck or is this a fluke?

Safari 6.0 won't Play .m3u8 files under Mountain Lion

I have embedd some streaming video in my web page, but it won't play in Safari 6.0 under Mountain Lion 10.8.1.
The streaming video shows just fine on my iPad 3 and on my iPhone 4, and it shows just fine in Safari 5.1.7 when I boot up under an earlier system version. In 10.8.1, however, all I see is the black "loading" bar, but nothing ever happens.
Any help will be appreciated.

I am getting the same issue.
In the new Mountain Lion update 10.8.2 it says that it fixes safari so that you can have it automatically open safari and it will open all last windows.
I did the update, I don't have that option still under my general settings in safari, when someone else did the update and they have that option to reopen last windows when opening safari...help please

Trackpad issues after mountain lion install

Since my Mountain Lion install, the trackpad on my 15" MBP will track, but won't select anything. Hot corners aren't working, the dock won't appear, etc. Anyone have any suggestions?

Got similar issues, no notifications and no switching between full screen apps (4fingerswipe). Some swipe features work, no secondary click in bottsom corners...Trackpad operational under Mountain Lion a total nuisance compared to Snow Leopard...PLease Apple, show some respect again to your faithfull customers and show some response!

Problems with WD software under Mountain Lion?

HI
I come from the Mavericks discussion, where someone wrote that WD software (for Western Digital hard drives) made not only problems under OS X 10.9 Mavericks (data loss!) but also under Mountain Lion. I'm using a WD My Book Studio II (2 x 1 TB as RAID 1) and until now had no problems under Mountaion Lion. Which problem could occur? Many thanks.

Personal experience, software not included... I've had terrible issues with WD drives. I say "software not included" because I've never used WD drive software.
I had an 80Gb internal that was seized up "out of the box", another that went "belly up" in less than six months, and a 500Gb MyBook that "croaked" on me in less than six weeks, costing me more than $25,000 worth of music.
Finder (in OS X from 10.2 to 10.9) should be able to manage the drive WITHOUT any proprietary software from the drive manufacturer. But that's ONLY if the drive doesn't malfunction, or you don't have any connection problems.

Start up Issues with Mountain Lion?

Having start up issues with Mountain Lion. Gray Screen and nothing happens.

If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Safe mode is slower than normal, and some things won’t work at all. Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the startup volume is on a software RAID, you can’t boot in safe mode. If you're able to boot, launch the Console application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. ☞ Open LaunchPad. Click Utilities, then Console in the icon grid. Select the most recent panic log under System Diagnostic Reports. Post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

HDMI Video corruption under Mountain Lion

I have a mid 2011 15 inch Macbook pro. Upgraded to Mountain Lion. I use an HDMI TV connection as an external monitor with the laptop closed. I switch to another work PC on the TV using the source selection. This causes the Mac to Sleep because no external monitor is detected. When returning to the mac and waking it up via a blue tooth track pad, the video is corrupted. It's just scrambled.
Unplugging the monitor and plugging it back in, doesn't help.
Unplugging the monitor, opening the mac, then plugging in the cable fixes it. I use a mini display port to HDMI connector.
This worked fine with no corruption under Lion - but it is easily reproducable with corruption under Mountain Lion.
Any advice?

Opening and closing the lid corrects the problem by causing the external monitor to refresh.
It doesn't have to be disconnected and reconnected.
The problem still occurs after the 10.8.1 update.

I have to input a password in order to log in each time I turn on my Macbook Pro Santa Rosa under Mountain Lion. Now my built-in keyboard suddenly doesn't respons at all. And the bluetooth function seems to activate automatically even though I turn it off

I have to input a password to log in to my Macbook Pro Santa Rosa under Mountain Lion. Now suddenly the built-in keyboard doesn't work at all so I cannot use my computer. I also notice that the bluetooth function is activated automatically even though I turn it off. It looks for an external keyboard. Please help me out. Many thanks!

I have the exact same problem trying to use the Remote app on both my iPhone 3gs and iPad 2 with either my Mac or ATV2. My Remote app used to work on my phone - I can't recall if I ever actually used it with my iPad, but when I tried today, I got all the same results as you did (on both iPad, and then iPhone). I was using my ATV2 to play music from iTunes on my Mac and wanted to use the Remote app, but it would not connect to either device no matter what I did.

Firewire, Virtual software and Chrome don't work under Mountain Lion. Why?

I upgraded two machines to Mountain Lion: A Core i7 iMac and a Core2Duo Mac Mini running OS X Server.
The first thing I noticed was that any virtual machine software icons - Fusion, Parallels and Virtual Box - show up with the circle crossed out, even though each version was the latest installed (came as part of a couple of MacUpdate bundles).
Then I noticed on the iMac, all firewire devices were not being seen. I have a Lacie 4big Quadra hooked up via firewire 800, an LG DVD+R drive on firewire 400 (800 to 400 cable coming out of the Lacie) and an EyeTV 200, which all were working just fine under Lion. System Profiler shows a "Maximum Speed: up to 800 Mb/sec", but no devices listed as available. I did dupe the original Lion installation to an external USB disk but haven't resorted to that yet. Tried identifying all connected devices at the command line, but haven't had success finding the firewire devices.
Finally, although the latest Safari is nice and fast, I have been accustomed to working with Google Chrome. On the iMac, every time I attempt to run Chrome, it comes up crashing and asking if I wanted to report it, which I do. I even went as far as to delete and reinstall Chrome and I get the same result. What's up with that?
Ideas?
Regards,
Tony.

Since posting, I found out there were some updates available from VMWare, Parallels and Oracle (VirtualBox) which now allow them to run properly under Mountain Lion.
I still have the problem with Firewire and Chrome though... For Chrome, I have deleted and reinstalled but get the same result. As for Firewire, I'm almost ready to "reorganize" my wiring from adding another powered hub and hooking some of the devices via USB, or just follow the lines and plugging and unplugging, although moments before the reboot from Lion to Mountain Lion, all firewire devices worked in the configuration described and nothing had since changed...
Regards,
Tony.

HT1338 Quicktime Player no longer plays under Mountain Lion

Quicktime Player no longer plays under Mountain Lion. It loads, I can see the video but it does not move when clicked on to advance. It does move page by page mannually with the arrow buttons but does not play when clicked on the video advance button.

Is this a known problem?
Yes, if you mean that the MOV file may contain data that is not supported by the QT X AV Foundation, Modernizer, and Convert 64-bit QT X structures embedded in the Mavericks and Yosemite operating systems but still supported by the 32-bit QT 7 structure still included in these operating systems and/or supported by the "open" codec configuration accessible by QT 7.
Has the format of mov files been changed?
I don't believe the file container format has changed but security updates and/or Mavericks/Yosemite codec support limitations may fail to recognize or support a particular file container/data compression format combination. Since you have not provided any information regarding the data actually contained in the MOV file, it is impossible to be more specific here. However, in most cases it is possible to use any of the available FFmpegX based transcoding utilities to manually convert unsupported data to file/compression combinations that are compatible with both QT X and QT 7 based apps under any current Mac OS X systems.

1080 60p AVCHD choppy only under Mountain Lion

1080 60p AVCHD .m2ts and .mov video playbacks, using VLC and QuickTime are choppy only under Mountain Lion.
The same videos used to playback smooth with VLC and QuickTime under 10.6.8 Snow Leopard and Sony PMB under BootCamp/XP so my 27" iMac with 12GB RAM and 512MB video RAM is not the problem.
Anyone has a solution to this? I'm thinking about going back to 10.6.8 Snow Leopard via TimeMachine.
Is there a way to assign more RAM to QuickTime, iMovie, VLC, or other media players since out of the 12GB RAM only 160MB was assigned to VLC and QuickTime during playback.
Thanks for your help!

These discussions show that the same video-playback problems started with Lion even on 2011 i7 27" iMac and continues to ML:
https://discussions.apple.com/message/16160679#16160679
https://discussions.apple.com/thread/3204054?start=0&tstart=0
I'm definitely going back to Snow Leopard and run Mountain Lion from a separate partition only when I need the ML-only Apple eBook app.
