Different optimization of audiofiles on different macbook Pros?

Has anybody noticed a difference in optimization of the audio files (m4a) between different Macs? I did :-(
I'm running IBA 2.1.1 on a mac book pro and noticed that a certain audio file get little artefacts in the final ibooks file. If I unzip the ibook and play the optimized mp4 files in itunes the quality is OK. In quicktime the artefacts also occur.
I asked a friend to make an ibook with the same audiofiles, there are no problems at all in the optimized files and ibook.
Could this have something to do with a difference in hardware configurations?
I have a lot of these files and really need them at high quality in my ibook, so I need all the help I can get ....

This is a pretty advanced question. I would post it to the
Flexcoders mailing list (if you haven't already) as there are some
charting gurus on that list that might have some input. The mailing
list can be found here:

I am now using a different MacBook Pro, and want to install my CC, I have done that and downloaded the Photoshop App but its a trial version. How do I get the full version of the apps?

I had a new MacBook Pro that was damaged and I am now using a different MacBook pro as my primary computer (running yosemite 10.10.1).
I did uninstall the Creative Cloud off the old MacBook before I stopped using it.
I have downloaded the Creative Cloud and signed in using my adobe username and password, but when I went to download the Photoshop App it is only giving me the TRIAL VERSION.
How do I make sure that the apps are the full version that I have already paid for? (I do know that my subscription is still current)
Thanks for your help

Shawn I would recommend utilizing the steps in Sign in, activation, or connection errors | CC, CS6, CS5.5 - http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html to resolve the connection error which is likely preventing the software from authenticating.

OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

WD My Passport 1TB USB external drive randomly ejects from my iMac and MacBook Pro.
The drive is approximately 4 years old. When the drive is plugged in, I can see the data. It appears to be working properly. The only problem is that everyone of my Apple Machines are ejecting it. Several years ago, this drive connected to Mac machines with no problems. I have tried two separate USB cords. I have updated the firmware. I have tried it on my MacBook, two different Macbook Pro's, and my iMac.
All give the same result of random ejection of the drive and the error message of:
Disk Not Ejected Properly
Eject "1TB Passport HD" before disconnecting or turning......
Searching through the web, it seems this is an common/known problem. Does anyone know the solution?
Thanks,

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

MacBook Pro won't boot with new hard drive, but a different MacBook Pro will

So here are the details. My friend and I both have 13-inch Mid 2010 MacBook Pro's. Same processor and specs since they were purchased at the same time, but originally had 250 GB hard drives. His hard drive failed and needed a new one. Put a 500 GB Seagate Momentus 5400.6 in his computer, and tried using a flash drive with "Install OS X Mavericks" on it to install Mavericks on his new hard drive. No matter what, it wouldn't install. I finally was able to install OS X 10.9.4 on it by connecting the new hard drive to my computer with a USB hard drive enclosure. I put the hard drive back inside his computer and it wouldn't boot (stuck on the gray screen with apple logo and a spinning wheel). I then attached to the hard drive to his computer externally with the USB enclosure, and then it booted and worked perfectly.
So, it seemed like the problem was with something inside his computer, but then I switched our drives, and that doesn't seem to be the case anymore. I put my original hard drive into his computer, and his new hard drive into my computer, and they both booted and worked perfectly, so I have no idea why his computer will not boot with the new hard drive internally.
To summarize, his computer boots with: 1) new hard drive connected externally (won't work if it's internal), and 2) my hard drive internally
but my computer boots with: 1) new hard drive connected externally AND internally, and 2) my hard drive internally.
Both hard drives have OS X 10.9.4 installed
If anyone has any idea what's causing this and how to make his computer work with the new hard drive internally that would be greatly appreciated.

So after switching the internal SATA cables from each computer, now we have
His computer, with my SATA cable:
1) Worked with every hard drive!
My computer, with his SATA cable:
1) Works with 1 TB Toshiba hard drive
2) Works with 500 GB Seagate hard drive
3) Works with my original hard drive
4) Flashing folder with question mark with his old hard drive
So it turns out you were right! Definitely had something to do with the SATA cables. But it's still strange that mine was able to boot with all the hard drives except the one that was originally in his. So it seems like it was some combination of his SATA cable and something else, since when his SATA cable was in his computer only 1 hard drive (my original) worked, and when it was in my computer, 3 hard drives worked. But at least its working, and I'm just gonna keep our SATA cables switched since that seems to work out fine

Different MacBook Pro Specs in Europe?

I was planning to finally update to the latest MacBook Pro model, buying from the German store, when I saw that the top-of-the-line 15" model lists a graphics card memory of 256 MB, not 512 MB, as in the American store. Same problem on the British Apple site. Is this just a snafu, or is Apple for some weird European Union reasons not offering a 512 MB card here?
Anyone who could clarify, I'd appreciate it.
Jake

Thanks for the comments, replies.
Just to reply to my own question, I checked the 'Compare Specs' section on both the German and British website, and there it lists the top-of-the-line 15" MacBook Pro as having 512 MB video card (and the basic model having 256 MB). So thankfully it looks like the Buy Page data is an error that'll be updated soon.

Different MacBook Pro, same harddisk?

I've got a MacBook Pro 13", and I have just bought a 15"; both are mid-2012 models. Is it possible to take the harddisk of my 13" and put it in my 15", without having to re-install OS X?

That's a pretty good assumption. Both originally came with Lion. Both will run with Yosemite.

Best way to sync files on 2 different MacBook Pros?

i use 2 macbook pros. what is the best way to keep files - docs, pdfs, psds - synced on both computers?

An external hard drive that you move between the two computers. Keep all the active files you're working on on the external drive. At the end of each working session, save copies of them to the computer's internal drive before moving to the other computer for your next work session.

Pages document not viewing properly on two different MacBook Pros

My colleague and I are working on a document that is located on our server. When I open the document the first page is different than we he opens the document. The text is there, but not in the proper position. The second page is identical on both machines. We are both using the same version of Pages and we are both using Mac Book Pro's his is about a year old, mine is a little over two years old...both Intel. It looks correct on his and incorrect on mine.
We are both using Snow Leopard 10.6.2, and we are both using Pages 09 v 4.03
Any ideas?

As a sidenote, the document in question is a newsletter and it appears that the issue is with the text boxes on the first page of the newsletter. The newsletter previews ok, but once it is open, the text within the boxes on page 1 is all over the place.
Any thoughts would be appreciated.

Multiple Hard Drive Failures on my Macbook Pro - Entourage reminders?

Over the past 2 months I've had three hard drives fail on three different macbook pro computers.
I've retraced my steps, searched many forums, and spoken with multiple Mac Geniuses but still can't figure out what's happening. The IT guy at work is about to kill me and I really want to figure out what's going wrong so I can fix it (or change my current behaviors).
Computer #1 - Out of the box, 2-3 weeks old. I took the computer home to do some work over the weekend. I didn't turn the it off before transporting it, but I did wait for it to go to sleep completely (I've since read that it takes a few moments while things in RAM switch over to the Hard Drive to save incase of power failure). I worked on it a bit at home, mostly just internet searches and a few word documents. When I returned to work my computer was running slowly and suddenly all of the programs locked. Since I've had this problem before with my personal computer (a G4 Powerbook), I tried the force quit options to no avail so I just held down the power key to power off. When I rebooted I got the dreaded "no" symbol.
Computer 2: IT gave me a used macbook pro that they repurposed for me. I made sure to shut down before transporting this computer. A few days later, before I even got to transfer all of my files, the computer started running slowly, programs locked. I eventually got the computer to shut itself down (as IT didn't want me to do a forced reboot) but upon restarting I got an even more dreaded screen, the folder with a question mark in it.
Computer 3: It was a fairly new computer, though a bit more ram, and probably only a few months old (used by a freelancer). It worked great. I took it home several times, transfered all of my files. Set up everything perfectly. Three weeks in, after working at my desk for about 4 hours, everything began to slow down. I called IT immediately and remotely sent a force shut down message. Nothing happened for about 15 minutes so I left for a meeting. I came back a few hours later and my computer was off. When it restarted, nothing appeared. There wasn't a "no" symbol or folder with a question mark in it, just a blank screen.
I've read and thought about all of the options.
- Large Magnet somewhere - It would have affected my personal computer (if at home) or my colleagues (if at work) or everyone else in nyc (while on the subway)
- Too hot - Possible I suppose, but how does running iTunes, powerpoint, and entourage do this?
- Downloaded something/Virus - We don't have administrative privileges. I can only update some software and send/receive folders. Plus, can any single file cause this much damage?
- Moved before asleep - This might have happened on the first computer, but I doubt it could happen to three. I always shut it down now before transporting, and I was sitting at my desk for hours before I had any trouble last time.
The one common factor that I haven't mentioned.
We use Entourage as a mail client here.
Each time the computer froze, the first things to freeze were the Entourage calendar reminders. Entourage seems to run strangely with the airport, but not with our LAN. When my computer froze last time, I had the aiport on but was working off the LAN. Could Entourage cause this much trouble? Has anyone else had trouble with entourage calendar reminders or failing hard drives?
Oh, and it also always happens on a Monday. I've taken the computers home multiple times though, so I'm not sure if it's something I'm doing during the transport or not, but the computer is always off now when I move it. I also cary my personal computer with me often, same routes and bags, so I'm not sure why it's not affected.
Thanks

How crap is that?
It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

My very new MacBook Pro will not acknowledge that I have my camera plugged in, so I am unable to download any pictures.

     This year for Christmas I recieved the newest version of the MacBook Pro. It has worked perfectly, until today. I went to download pictures off of my camera on to my computer, and the computer would not acknowledge that anything was plugged in. I tried each USB port, I restarted and shut down the computer several times, I left it in for a while without touching it, I tried logging in as a guest user, and I tried using a Card Reader instead of the camera cord. But absolutely nothing worked.
     I found that the problem wasn't the camera cord or camera, because I tried plugging it into a different MacBook Pro and it worked just fine. I had the computer plugging in the entire time so it couldn't have been that the computer was just low on power. The really weird thing is I tried to plug my iphone into my computer and that worked fine.
     Has this ever happened to anyone before? Can you give me some advice? I am very frustrated because this computer is basically brand new and its supposed to be a very high quality computer.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Magsafe 2 for retina display macbook pro

I've had two different MacBook Pro's since 2006... I went through 4 magsafe power adapters as the cable coming straight off the connector always began to permanently bend at the magsafe connection point such that I didn't trust it from an electrical safety point of view (after seeing one arc at that point a time or two). Then when I bought what would be my 5th power adapter, much to my positive surprise, Apple had done a redesign that had the cable coming out at a right angle with repect to the way the older ones had the cable come out... They also beefed up how the cable comes out of the magsafe end.
Now I see a picture of the 85W power adapter for the new Retina display macbook pro I am planning to buy soon... And it looks like they've reverted to the old "wire straight out from the connector" approach...
Is that true??? That would be a significant step backward for me as where I have to plug in my mac (to the right of where I sit) having a straight cable coming out from the left of the mac is just going to cause me to start wasting power adapters again...
Might I be able to continue to use the 85W power adapter I currently have on my 17 inch 2009 macbook pro??? And it's not the original power adapter but one I bought maybe in 2011 or so... I love this one where the cable leaves in the direction heading out away from the top of the mac rather than the ones that came out straight to the left... And the picture of the new one appears to come out straight to the left again...
And what do you even call the power adapter I have that I bought in about 2011 where the cable comes out at a right angle to the magsafe connector itself???
Any help folks can provide on the questions above would be much appreciated... thanks... bob...

Ahhh, remember the Mac Pro from a few years ago that used a refrigerant?
And a number of years ago the Cray XMP and YMP had all of the cpus immersed in refrigerants because they ran so hot they were melting the solder and chips. Those were something to run on...unbelievable speed, well for that point in time.
I used to have a watch that had more computing power than the IBM 1620 I first learned to program on.

IPhone 4S not recognized by MacBook Pro

Mac OS X Lion - Version 10.7.4
iPhone 4S
Tried troubleshooting all over the internet on this one and have finally given up after countless attempts. Any help here would be greatly appreciated.
So my iPhone 4S works fine with one exception, it will not take a charge or sync on my MacBook Pro anymore. Not sure what I did (or what update did it) but I'd like to fix the issue if possible.
I have an iPod shuffle, iTouch and iPad 2, all of which sync fine on the MacBook Pro.
The iPhone 4S charges in my car, through all wall outlets and is set up on iCloud and syncs fine with iPhoto, iCal, and any purchases made on iTunes. The big reason I need to get this fixed is to move the videos I have on my iPhone onto my MacBook.
I've tried different cords, restarting both the MacBook Pro and iPhone, resetting the iPhone etc. etc.
I'm at a loss other than taking the iPhone and MacBook into an Apple store. I feel like I've read countless threads on this same issue but no real fixes.
Does anyone have a solution?

Thought I would add a quick update.
I tried plugging my iPhone 4S into a different MacBook Pro and no response there either.
Safe to assume it's the phone at this point???
Think I may just take it to the Apple Store if nobody has any ideas.

Which Macbook Pro to buy as a college student?

There are 3 different Macbook Pro's out there that I can buy with the rebate / reduced price / free iPod Touch. The problem is I don't know which one to buy. Many people said that the difference between a 2.4 and 2.5 core 2 duo cpu is only 5%. Then there is a bit of difference from 256mb to 512mb of the 8600m graphics card.
Basically I will outline what I will be needing from a laptop so you guys can help me make the right decision. But for now before I say what the outline is, you bought your Macbook Pro; did you choose the right one? If you didn't and you could go back in time, which one would you have bought?
Anyways, obviously the laptop is for college work. So Microsoft Word, Powerpoint, Photoshop and such. But of course there will be some gaming here and there. I am a Blizzard fanatic and I only play Blizzard games. From diablo 2, starcraft and now Warcraft 3 is pretty much all I play. I am not even going to try WoW as it could probably ruin my college carreer.
But the game I'm really anticipating is Starcraft 2. Which Macbook Pro would be able to handle that game in your opinion?
But I hope these information is good enough so you guys will know which one I should buy. But if you guys have any other questions on what I will be using the MBP for then let me know so I can help you help me pick the right decision.
Thanks!

If you're going to use your new laptop for college use/gaming/general use, my recommendation is going for the $1799 MacBook Pro 2.4GHz. I recommend this one over the others for a few reasons. As mentioned previously, the 0.1GHz in processor speed in essentially unnoticeable. With regard to RAM, its always best to have your system maxed out in order to achieve its full capacity. However, I do recommend going through www.otherworldcomputing.com or a 3rd party RAM merchant to purchase your additional RAM. You can get it for a drastically reduced price there, and then have an AASP install it for you. Bear in mind that installing RAM yourself could void your warranty. My point about the RAM is, the 2GB standard in the $1799 MBP version is sufficient. Also, the graphics card. 256MB should be sufficient to support your gaming, and unless you plan on getting a large display, it shouldn't be necessary to double the VRAM. So, based on the information you provided, the lower-end model should be plenty enough for your needs. Hope this helps.

MacBook Pro Snow Leopard battery life

Okay, I've been poring through the threads for days now to try to find a solution to this . . .
I have two different MacBook Pros (a 15" 4,1 and and a 17" 1,2). I've upgraded both to Snow Leopard. Each is now running 10.6.6.
After uprading, both started suffering extremely poor battery life, losing nearly 1% each minute, even when the Mac is sitting and doing nothing.
I've done all the fixes I've found (recalibrating the battery, resetting PRAM, checking for rogue processes, etc.), and so far nothing has fixed the problem. I even bought a new battery for the older Mac, and that had absolutely no effect.
Some of the threads I've seen here go back for more than two years.
Has anyone solved this problem? I'm at the end of my rope!

1% a minute?
You're quite right - this problem has existed for years. Apple bases its power estimates on a device half intensity, using Energy Saver, and SL is supposed to have better battery performance than Lion.
Something is causing your battery to die on you. Check off the following one by one to make sure there isn't another problem:
1. Are you attached by USB? If you leave your MBP attached to a USB device or Firewire cable, you can lose battery power even if your computer sleeps. Disconnect all devices when you're not using them.
2. Are you using Energy Saver? Your machine may be sapping energy by being at high intensity. Instead, opt for a monitor at half or three-quarters brightness.
3. Losing battery even while sleeping? That problem can be addressed by going to System Preferences/Bluetooth and disabling Bluetooth.
4. Are you losing battery through heat? You can lose battery capacity with a system that's hot all the time. Keep your machines as cool as possible, through energy management, getting a laptop cooler, or using free applications like Fan Control.
5. Limit your losses. Use a power cord whenever convenient to increase your real-life battery time.
6. Some applications, like Skype that are on all day, sap battery power. If one such application is on all day (or close to it), this may be part of the issue.
7. Don't upgrade to Lion. This OS demands twice as much power as SL.
I don't want to minimize the significance of the issue, but take a look at which processes are drawing power. You might want to go to Utilities/Activity Monitor at take a look at which applications are consuming your CPU.
