Mac still frezzes after reseting SMC and PRAM
hi everyone!
I'm kind of noob here but my story is...
My macbook pro is a mid 2012 and i am having a strange problem. My mac started to became slow and constantly showing the spinning pinwheel in every move. So i've changed the hd (that originally is a 500gb 5200rpm) for a 160gb that i've found in my home.
I've changed it and re-installed the OS X Mavericks and the spinning pinwheel still show up. So I've decide to reset the SMC ( with the original hd) and no sign of change, reset the PRAM and still the same, then I've re-installed in the 500gb hd the OS X and get back to normal, but that was yesterday.
Today the pinwheel show it up again...
I am going to buy a new hd but I'm afraid that nothing changes.
If anyone have a idea, i'll thx a lot!
Sup guys!
Well, i've bought the hd and that resolved the issue, so that was the solution for this one!
bye!

Macbook wont start -- have to reset SMC and PRAM
Hi,
Sometimes, when I try to switch on the laptop, it wont start.. Nothing happens.
After reseting the PRAM and SMC, it comes up. But the issue is for the last 3days, I have to do this everytime.
Can you help me out on this one? Sometimes, I had to wait for like 5-7 minutes and then I have to switch on the laptop after reseting.
I dont know, whether it is affecting my laptop h/w.
I bought this 5months ago. its Macbook Air Mid 2013 model.Hello there, tcpipv6.
The following Knowledge Base article offers up a good number of steps to try for troubleshooting issues with your MacBook not turning on:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/TS1367
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Reset the SMC.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

PPC G5 quad will not start up after resetting SMU AND PRAM
Hi folks
I been having issues with my G5, where it would freeze up unexpectedly and then the fans would come on full tilt.
I received some advice about resetting the SMU and the PRAM.
Now my mac dose not get past the grey screen. I have to hard drives attaches one has OS 10.4.11 the other has Leopard.
Odd thing about the Pram is I never got the mac to re-chime.
Also I was advised at the apple store to disconnect power for 30 sec and then hold the power button on for 20 sec after the restarting. I heard an odd tone and then the fans came on.
Btw this model does have the SMU button which I pressed when the power was off.
As the unit will not run with the fans removed.
Any suggestions?
Much appreciated
12 gig of ram in the 8 slots. All FireWire , Ethernet and USB disconnectedThere is a battery that makes the PRAM work. You may need to replace the battery.
You may also need to limit your RAM to two 1 GB modules, making sure they are made for the PowerMac G5 of your machine's age. Not all 533 MHz PC2-4200 DDR2 SDRAM. will work with the machine, it has to be specifically made by the age of the Mac model, and Mac model name according to the vendor. Thus if you have a Quad Core Mac from 2005, that's what you need to buy RAM for. Do not buy 533 Mhz PC2-4200 RAM just because it says it is that.
http://www.crucial.com/ and http://www.macsales.com/ specify the model and age of Mac in their store.
Others may too, but do not have ValueRAM or non-lifetime warranty RAM.
Lastly, your model may have liquid coolent that has run out or gotten old, making it not boot. If unsure where it is, ask an authorized service center. Some have leaks and won't boot at all. -
HT3964 fan still running after resetting SMC?
After booting up Macbook the fan immediately starts running fast. Closed down all programmes and reset the SMC. Fan still continues running. Has anyone else experienced his and has a solution?
Run Apple Hardware Test. Maybe it will detect a bad sensor (just maybe).

Why does my Mac not restart after resetting SMC ?
I have a MacBook white intel base 2.4 duo mid 2008. I reset the SMC because the message kept coming that was going to shutdown. If you did not select cancel it would shutdown. Since then it will not restart? The choices were sleep , cancel or shutdown . Performe all the trouble shooting I could find it still came up with message
Any ideas
Regards
Denishow did you do the SMC reset? the following article tells how to do this:
http://support.apple.com/kb/HT3964
use the section for batteries that can be removed to perform the reset then see if it will start up
if it doesn't what OS are you running? -
I recently upgraded to Mavericks on my macmini and suddenly it won't connect to my home wifi network. It says I need to move closer to my router whioch is really close and it worked fine before so I doubt this is the issue. Also, my IPad and Macbook connect just fine to the network, so it seems like its localized to my macmini and now funny enough my IPhone. I tried reseting SMC and PRAM, but this didn't help at all. Any helpful suggestions?

Hi,
Can anyone have list of symptoms that may help a user to determine if there is a need to reset the SMC and PRAM.

Regarding the start up sound, i opened the L Bracket but Ram was seated properly. I just checked the ram's position but didn't remove it. However, i found the right most screw of the L-bracket was loosen, i don't know how.
Do you think i should remove the ram and reinsert it? If so, do i have to reset the PRAM after that?
The system profiler shows the ram is ok-
BANK 0/DIMM0:
Size: 512 MB

What do you think about the whole situation?
Look forward to your reply.
All the best and have a goo day Mate. -

After reseting smc the camera still doesn't work
in every camera application it says "no connected camera" i tried resetting the smc and it still isnt working. any suggestions?

Although you may have tried other suggestions from http://support.apple.com/kb/HT2090, you do not mention that you have checked more than one user account. You could check your user account before responding to Klaus for more specific help suggestions.
(Over time, Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD." Regardless of the name of your Mac's built-in camera, the same info and troubleshooting applies.)
Do not use the "Guest" account for user account testing. If you don't already have multiple accounts, create a new account for this testing. If you need help creating a new user account, see http://support.apple.com/kb/VI32

Sound still bad after resetting PRAM
Yesterday the sound on my laptop speakers began sounding really bad (almost like it's crackling?) and after resetting the PRAM and resetting the audio through a command on Terminal, it still sounded bad. It made me think it was a problem with the speakers themselves but now that I'm using my headphones it's still pretty bad. What do I do? Is there a way to fix this without having to take it in for repairs?
That's good : these articles explain in more detail.
