Why is it impossible to connect a MacBook Pro running OSX 10.8.5 to a Panasonic projector using VGA adapter?
A few of us tried for 45 minutes to connect a BMP to a Panasonic PT-F200NT projector.
Please help.
Display options didn't work.
Computer search on the projector remote didn't work.
The button to automatically find connected devices didn't work.
Changing the VGA connection didn't work.
Turning off the projector, then turning on again with the cable and VGA adapter plugged into the computer didn't work.
Selecting computer 1 or computer 2 didn't work.
Pressing F7 or fn+F7 didn't work, neither did and other combination of fn+F#, or alt+F#.
Unpluggin and pluggin in again didn't work.
What does work?
Why is it that when conncting to projectors all Windows machines work perfectly, without any trouble every time, but Mac machines always cause trouble.
Why is it that Mountain Lion (OSX 10.8.5) makes it harder than previous OSs?
If you have any suggestions that would be great, thanks.
Thank you.
Other advice I've had is to keep unpluggin it and plugging it in again (thunderbolt adapter).
I'm nowhere better than I was before.
I guess it's just as you say (how I'm interpretting what you say):
The Thunderbolt adapters are just poorly made.
It works 50 % of the time, maybe they have random number generators in them centred on 1, and they only work if the random number is 1.

Have a macbook pro running osx lion. Connected a Kindle Fire using micro usb and the disk icon doesn't show up on the desktop. Also sometimes get a message sayiing computer doesn't recognize device. When I opened disk utilities the Kindle disk does show up there. What am I missing?

Precisely why it's not an iPad, and why it doesn't cost very much. An Apple rep would tell you how to connect an iPad to every computer.

I'm trying to connect my MacBook Pro running on OS 10.8.2 to a Linksys EA3500 router and when I go to click on the set up icon I get an "unsupported operating system". Any suggestions on what to do? The Linksys site is useless. Do I need some kind of upgrade?
Don't use the CD software its not necessary.
Infact put it in the trash.
Your router will have an IP address in the range 192.168.1.1
Connect your router to your Mac via Ethernet cable (They usually supply one with the router and don't worry which end goes where the Mac LAN socket is bi-directional)
Also connect your router to your telephone line.
Now open your Web browser Safari . Type in the IP address above and a Javascript control panel will launch
Enter the default password and username (They are on a label on the router )
Your now have the ability to set up your router.
Your will need the password and user name supplied to you by your ISP at a minimum.
Enter these and most modern routers automatically configure the basic networking setting.
You now need to go to the security setting and set this as WPA2 Personal (NOT Enterprise) or WPA2 with AES and TKIP which ever it refers to and create a pass-phase. WRITE it down
You should be online.
Now remove the cable and connect to the Wifi and enter that passphase. -
My macbook pro running OS X 10.8.3 freezes when I plug an adapter into the displayport, even when nothing is connected to the other (vga) end. Anyone know a solution? I have used this adapter with a macbook air and it works flawlessly, but the moment I plug into the minidisplayport the macbook pro freezes with a little spinning color wheel that goes on and on. . .
Hello there, sarhang27753.
First thing that would come to mind to resolve the issue would be SMC and PRAM resets. I've linked Knowledge Base articles below:
SMC

PRAM

What cable should be used to connect a macbook pro, 13 inch, early 2011 model to an external projector so the project displays the image on the computer screen?
You will need a cable or adapter with a minidisplay connection for the MBP. That will be inserted in the Thunderbolt port. The other end is dependent upon the connections of the projector which you have not listed.

I have a 2010 macbook pro running osx 10.6.8 and would like to interface my mac to my HD tv. Are any instructions available to reliably make this connection and if so what is needed on my part. Is the software compatible or do I have to upgrade to a later version OS. Thank You,
GeneI purchased a mini to HDMI cable and tried to connect to the TV but the TV is not recognizing the computer. I attempted to set sound and display settings under the "my Preferences" utility with no success. Again, I'm not sure if I need to upgrade my OS software Any Suggestions?

Hi. I've been traveling, using facbook on iphone and my macbook. Suddenly I cannot access Facebook. I prefer to use Safari as my broser, but I downloaded Mozilla tonight to just see if it was a browser issue. The problem carries over into Mozilla Firefox. Both say they can't find the server. However, I can access facebook through my iPhone.
Can anyone help me so I can use facebook through my computer--I'd like to use it on my computer. I use Macbook Pro running OSX 10.8.4. iPhone is iPhone 5 running 6.1.4.
Thanks,
ESTTry enabling the Personal Hotspot on the iPhone and connecting the Mac to the Internet thru it. If Facebook works ok then, that would mean the ISP is either blocking or having connection problems whereas the phone carrier is not.
Be mindful that carrier data charges can be outrageous so use this as a test first. -
After upgrading iPhoto on my MacBook Pro running OSX Yosemite 10.10.3 it continually keeps asking me that it is preparing library. This has happened 5 times now and I can't access my photo's through iPhoto, any suggestions?
There is no upgrade to iPhoto with OS X 10.10.3 - here was an update to version 9.6.1 a few months ago and Photo 1.0 was added with 10.10.3 - what software and which version are you having trouble with - iPhoto or Photos?

when printing from aperture my margins are unequal, even if i set my margins they come out bigger one side and not the other. i am using a macbook pro running osx lion and printing with a canon pro 9000.
please can anbody help or advise?You didn't mention any color calibration being done on your monitor. This is an essential part of any color-correct workflow. What are you using to calibrate your monitor (and your printer)?
Print profiles (for soft-proofing as well as printing) are for specific combinations of paper & printer. The nine you have are each, most likely, for a common paper (perhaps mfr'd by Canon) to be used with your printer.
I don't know what you mean when you say "I choose a high standard print option".
Have you read the User Manual chapter on printing?
Printing Your Images
There is also a good appendix on calibration:

O2 Connection Manager - Macbook Pro 2013 OSX 10.9
Hi all,
I don't seem to be able to get "O2 Connection Manager" to work on a new Macbook Pro (running Mavericks). It worked on my 2011 Mac with Lion and still does on my Win 8 PC (used for testing the dongle!).
Each time I try to open the [O2] connection manager I am left with an error message "thebillingday is a required value." before the application closes. Unfortunately, you cannot set the Billing Date until you (successfully) open the programme - which is something I'm unable to do due to the crash.
After a gruelling experience with the 'helpful' O2 support team, I'm informed they are under the impression that this software 'works fine' and it is not something they can help with (and that took three people and over an hour!).
I suspect that this may be a compatibility issue, however, on the off chance (as I'm stuck without internet whilst out of the office until O2 decide they need to update their software) - has anyone managed to get this to work on Mavericks?
O2 Connection Manager version: 8.8
Many thanks,
RobSo here is where I now am: when I bought them a couple of days ago, neither of the two (identical) dongles (both Alcatel X230D) worked properly in my Mac (a 2011 MBP, running OSX 10.9.1). The dongle did not show up in Finder, but did make an appearance in System Preferences>Network as an "HSPA Data Card", but hitting the "Connect" button here resulted in a "device does not exist" error message.
But they both worked just fine in my other latop, which is an Acer running Windows 8. And when I took the new SIM cards out of the new Alcatel dongles and put them in my (3 year old) Huawei PAYG O2 dongle and connected it to my Mac, they both worked just fine through the existing O2 Connection Manager.
Now what I've discovered today is that if I now plug the new Alcatel dongle into my Mac, then go to System Preferences>Network>HSPA Data Card and check the box marked "Show modem status in Menu bar", then take the dongle out of the USB port, then put it back in the USB port, then go to the Modem Status icon on the Menu bar and click on "Connect HSPA Data Card", hey presto, it connects to the O2 3G network. But despite this, the dongle is still not present in Finder and cannot be controlled via the O2 Connection Manager, as the O2 Connection Manager cannot see it.
But I can connect now, so that's a big plus. -
Kernel_task running above 500% CPU load on my Macbook Pro running OSX 10.9.4
I recently upgrade my Macbook Pro to OSX 9.0.4 and the system is running sluggishly slow, Activity Monitor showing kernel_task always running above 500% CPU load, system fan always running loud at startup but laptop is not overheating. Below is the EtreCheck report, hoping if anyone can help me fix this issue, much appreciate it. Btw, I have done the SMC reset, but nothing has helped.

0 B Page-outsThe kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display. -
My mid 2010 Macbook pro running OSX 10.8.4 sd card reader will not work
I have a Macbook Pro 13" mid 2010 model running OSX 10.8.4. I don't use the card reader very often so I can't tell you the last time it worked, but I have used it a few times without issue. (probably not for at least a year though)
I searched the forums and it seems this was an older problem with lots of suggested fixes. I tried blowing air through the slot and I also went looking for XQuartz but cannot find it under my utilities. (I assume it must be in the X11 category that is no longer supported under 10.8.4?)
I have tried putting it in all the way and pulling it out slightly as one person suggested and that also did not work.
Any ideas? For the first time in a long time I need the card slot and it doesn't feel like cooperating. LOL
edited to add that I am trying to access a Sony SDHC 32GB card model SF-32NX
Thanks in advance,
WayneIf you haven't already done so, eject the card by dragging its icon to the Eject icon in the Dock (where the Trash icon usually is.) Make sure the write-lock switch on the card is in the unlocked position. Then reinsert the card and test.
If there's no change, and the same happens with more than one card, the card reader is stuck in write-locked mode. I don't generally advise do-it-yourself hardware repair, but one ASC member managed to fix this problem. I haven't tried the fix myself and I can't offer any guidance beyond what's in that discussion. If you cause damage, don't expect your warranty to cover it. I suggest you instead make a "Genius" appointment at an Apple Store. -

Ask Dell who made the printer and what model is it. Then you can see if there is a matching driver provided with OS X or that can be downloaded from the manufacturer's website.

Headset Creative Bluetooth impossible to connect on macBook Pro
I bought a headset Creative 350 Bluetooth to be used on my MacBook Pro.
After installing headset, I get a message from my computer as following :

We testing the headset with other devices like Ipad, Iphone, it works perfectly.
Probably the problem comes from my desktop.
Does somebody knows about it ?You can change the width of the sidebar, but I agree there are things they could do with the design for smaller screens. I have an older MBP 15" with a 1440x900 display and I feel like I don't have enough room at times. Mostly my complaint is with the Files Panel because I work with a lot of content management systems with deep file structures. Nothing you can do, but I don't really think CC is a lot worse than CS6.
