Very poor video podcast performance

Computer is older (P3/1000, ATI 9550 video@1280x1024, Win2K, Quicktime 7.1.5.) Yes, I am looking at getting a new computer this summer, after some of the Vista issues are more settled.
I am having major issues trying to play simple video podcasts. Most of these are only 128K, such as Vintage Toons. Playing them results in 90%+ CPU, and only if I keep it original size and only play it directly in Quicktime player or RealPlayer. Playing them in iTunes is impossible, as iTunes itself is a major CPU hog. Doing most anything causes the video to freeze and sputter and even disappear. RealPlayer works best (I can even move the video around while playing without it stopping!) I can't play anything full-screen cleanly.
Quicktime is set to use DirectX, and Windows and DirectX are up to date. The video drivers are Catalyst 5.8. I don't think there is anything in the newer Catalyst drivers that will do much for an entry-level card like this.
This seems to have gotten MUCH worse with the latest iTunes/Quicktime upgrade.
I can play much higher bitrate (1M+) Windows Media files with few if any glitches.
Windows 2000

Most new QuickTime files use H.264 Video codec which cause a strain on older machines and graphic cards (and drivers).
Not much you can do except upgrade your machine.
You may be able to mitigate performance issues by setting QuickTime Preferences to not use DirectX (QuickTime Control Panel).

Very poor video quality after transcoding in Adobe Encore CS5.1

MERRY CHRISTMAS AND A HAPPY NEW YEAR!
I have very poor video quality after transcoding the video file (MPEG) in Adobe Encore CS5.1. Below you see my used settings in my filmproject.
The problem exists after transcoding in Adobe Encore CS5.1. I checked all steps and found out that there is no problem until transcoding. My exported file in MPEG has very good video and audio quality.
Facts:
1. Camcorder: Panasonic AG-AC160AEJ
Operating System : Windows 7, 64 Bit, Ultimate edition
Source files: MTS files
Recording settings (clip settings):
Type: MPEG Movie
Image Size: 1920 x 1080
Frame Rate: 25,00
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Pixel Aspect Ratio: 1,0
2. Sequence settings in Premiere Pro
Sequence was created from Clip directly with settings above.
3. Exporting settings in Adobe Premiere Pro:
Match sequence settings was activated. Now other changes were set.
4. Exported File:
Video
Image Size: 1920 x 1080
Data Transfer Rate: 25920 kBit / s
Frame rate: 25
Audio:
Bit rate: 384 kBit / s
Channels: 2 (stereo)
Frequence: 48 kHz
5. Transcoding settings in Adobe Encore:
I used different transcoding settings such as automatic DVD Transcoding, CBR and VBR.I also set “use maximum render quality”. But all results were always the same: very poor quality.
Why does the encore transcoding cause such bad video quality?
How can I solve this problem?
Please help me soon.
Best regards.

Hi Ann,
1) I did not only „Automatic (based on source)“ options in my tests, but also many other customized options.
The results are very poor. I have done a new test with the following settings. The result is also poor:
Download link: http://www.klavierlehrer-bayern.de/download/test_mpeg2dvd_1.m2v
Export Settings:
Format: MPEG2-DVD
Preset: Custom
Codec: MainConcept MPEG Video, Quality: 5
Frame Rate: 25 fps
Field Order: Upper
Pixel Aspect Ratio: Automatic (based on source)
Render at Maximum Rate: [active]
Bitrate Encoding: VBR, 2 pass
Minimum Bitrate (Mbps): 5
Target Bitrate (Mbps): 9
Maximum Bitrate (Mbps): 9
GOP Settings
M Frames: 4
N Frames: 12
Use Maximum Render Quality: [active]
Multiplexer: None
2) Why shouldn’t I use the “Match Sequence Settings” in exporting? Because of the big output file size?
I used it and the results are very good as I expected:
Download link: http://www.klavierlehrer-bayern.de/download/test_MatchSequenceSettings.mpeg
Export Settings
Match Sequence Settings [selected]
1920 x 1080, 25 fps, Upper, Quality 50
User Maximum Render Quality: [active]
3) I tried also Dynamic Link in PremierePro (to Encore).
The results are also poor.
4) I will test also LagarithLoslessCodec and frameserving +DGMPGDec. But the video is vertical long drawn-ot.
I think I did not use it correctly.

Very poor SMB share performance on 3TB time capsule.

Hi,
Is the SMB shares performance on time capsule suposed to be very poor compared to the AFP shares?
My TC will to around 9MB/s transfers using AFP, but on SMB it will do around 1.25MB/s (varies from a few KB/s to peaks of 4MB/s).
I tested both protocols using a ethernet cable connected from my macbook pro directly to the TC.
This is a 3TB time capsule runing firmware 7.6.1, and I did a factory reset before my tests.
Time machine backups were disabled during the tests.
I need SMB for my WDTV media players.

I would not say it is supposed to be.. but you are probably correct that it is very poor.. This issue crops up time and again,,, but not from people running Macs generally.. it is windows that is the problem.
A few things to check.
1. Are the names actually SMB correct?? ie short, no spaces, pure alphanumeric. Both TC name and wireless names if you use wireless.
2. Workgroup set correctly. ie WORKGROUP .. this probably doesn't come up with the Mac but affects most PC connections and possibly the WD TV
3. How old is the TC? If it is an early release Gen 4, you can take it back to 7.5.2 firmware.. frankly much of the trouble was introduced with Lion.. as they changed the SAMBA setup.. I would test from the WDTV.. or a PC.. if it doesn't glitch you are doing better than the Mac can do.. ie the reading in the Mac is pure Lion Lunacy.. https://discussions.apple.com/thread/3206668?start=0&tstart=0
One of those apple changes that shows.. they hardly test anything anymore. Do a google search for Lion SMB fix.

Very poor Random IO performance of 24 HDD Mirror-2 CSV on Win2012 R2 (Solved)

We already have a 2 separate Win2012 Mirror-2 Storage Clusters (in production) and had noted that performance was very poor.
We were looking to upgrade to Win2012R2 and storage tiering, we wanted to understand why the storage systems were performing so poorly. So, we have not built out a new storage cluster, with 2 nodes, 3 JBODs and 24 x2TB Seagate ES2 SAS drives.
We have run IOMeter to measure IOPs and the numbers are very poor, regardless of the 'geometries' we choose. Our Write IOPs results for 16KB block (this our typical DB page size) are:
2 columns, 64KB Interleave = 1043
2 columns, 256KB Interleave = 1176
4 columns, 64KB Interleave = 1424
4 columns, 256KB Interleave = 1688
8 columns, 256KB Interleave = 1677
We only tested Write IO because this should be the slowest/worse case IOPs values.
We also tested each HDD individually and they range between 270 and 330 IOPs.
By our math, the IOPs values should be in the range of 3000-3600 == 24 HDDs x IOPs/HDD div by 2 [for mirror-2], but the tested are showing values which are barely 50% of this.
Any assistance/tips would be appreciated.

16KB I/Os never touch the whole RAID stripe so that's why you see virtually never performance increase (I;m surprised you actually see any). Try using bigger request size to see would it make any difference. You need multiple workers and deep I/O queues.
What are you I/O Meter settings for test except write size?

Very poor video streaming from youtube

I cannot watch a single video from youtube or any other site. I have OS v6.0.0.522. Is there anything i can do?? It will play a video for a few seconds then just starts to buffer. I have a BB 3G 9300 with Sprint

Hello mikeswitzer. Welcome to the Apple Discussions!
As you have already figured out poor signal strength equals poor bandwidth performance. This, of course, will be noticeable for both audio and video streaming.
I suggest downloading a copy of iStumbler. Use iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at different points around your house, by performing a simple RF site survey. Within the Inspector, note the values for "signal" & "noise" at these locations. Start with your MacBook near the Time Capsule (TC), note the readings, and then, go to the location where you currently have the Mac Mini.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the MacBook, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at the Mac Mini, then you should be getting reasonable performance from your TC. If less, either try to locate the source of the Wi-Fi interference or try relocating either the TC or the Mac Mini until they are within a 20dB SNR range.
Another option is to utilize a transceiver on the Mac Mini to try to increase the Mini's built-in AirPort antenna ability to pick up the signal from the TC. One vendor that provides these is QuickerTek.

Very Poor Final Cut Performance

We just upgraded to a Final Cut system from an older Avid system, but it seems to be performing well below expectations. If anyone could make suggestions, they would be greatly appreciated.
Syptoms:
- Dropping frames on virtually every application, from mere audio to standard def.
- a weird flicker when playback stops (the screen goes black then refreshes with expected picture)
- choppy edges on resized windows. (Real-time but it doesn't ask for a render)
- Difference in color between paused video and playing video. (The playback appears to be the "correct" color)
Explination of system:
Apple G5 running mac os 10.4.3
Dual 2.3 Ghz Processor
2.5 gigs memory
ATI X850XT Video Card
Blackmagic's Decklink HD Pro
Blackmagic's HD Link
Final Cut Studio (Final Cut Pro 5)
The boot drive is an internal SATA 250 Gig Drive. This is where the Final Cut Application is.
Our scratch disk is a RAID using 6 external SATA drives controlled by a Tempo card. A Blackmagic Speed test returned 377 MB/sec read and 376 MB/sec write on these drives, so I don't think it's a bandwith issue. Drives are formatted without Journalling enabled.
All drives are new, optimized, and have been verified by Diskwarrior and Apple's Disk Utility.
I have also checked that each of the High performance PCI cards is in the right slot to optimize performance.
Things I've thought about but would like some input-
Is there a software cap that I haven't turned off?
Do I need to set up the Final Cut Application on the RAID Drive? (For quicker access to, say, preference files)
Could this be a symptom of a corrupt preference file?
Powermac G5 Dual 2.3 Ghz Mac OS X (10.4.3)

Welcome to the Forum.
I am sure you will be able to work at full throttle very soon. If my suggestion does not help I am sure someone will recognize your issue.
My suggestion is based on seeing pretty much what you describe in someone else's system and so I am offering the fix that worked.
The scenario you describe may reflect the operation of another application that is as hungry for "bandwith" and space as FCP. If you haven't, try turning Spotlight off. I also suggest that you trash the FCP preferences and repair permissions The last two can do no harm.

Very Poor Video

My video starts out okay then quickly disintegrates to a very delayed signal. I checked Audio, Connection Doctor, and my bit rate and frame rates are about 1/10 the rate they should be.
I have checked with Apple tech. support and they have no answers. I checked with my local Apple retail store and they had no answer. It's as if my connection to the internet is being squeezed and only allowing the data through at a very reduced rate.
Any suggestions??

This is very frustrating,
I have the same problem with frame rate dropping to almost standstill after a few seconds. The other end is fine.
I am using iChat on my Mac mini on the same wireless network (under Leopard) with no problem so no issues with ISP, Modem/Router.
I've played with the QT settings as suggested but no luck.
This happened a month or two back and just as I was cloning the system, my hard drive died. I thought the flaky behaviour might have been related to the drive as when the new drive went in things were resolved. Now I've mysteriously got the problem back.
I've reverted to a known good system copy with no iChat/QT plug-ins and the problem is still here. I'm on 10.4.10 on my PowerBook.
iChat was the only reliable contact that my kids here in Oz have with their Granny in the UK. It drives me mad that this has become so unstable!

Very poor 802.11n performance

I'm having difficulties with my time capsule. The performance seems very erratic. Due to me having also having a powerbook I've so far run it in compatible mode.
But the many problems regarding signal strength and a stable throughput struggling to keep above 485 kb/s prompted me to move the Time Capsule closer to the Powerbook so I could hook it up via cable and completely switch to 802.11n 5ghz, connceting the other computers wirelessly.
Unfortunately, it doesn't work. The performance is laughable, I get a mere 5000 kb/s down (internet based test) whereas I normally (2.4 ghz n/b/g compatibel) i get just under 2 MB/s.
Sending files to and from a connected harddrive is also very very very slow.
What is wrong with the Time Capsule? Is it interference from the (bastards) around me that all have their routers setup to automatically chose channel?
Is my time capsule broken? Is my computer broken? What is wrong?
I'm close to returning the device.

I've just completed an experiment.
Two iMacs side-by-side. One with Airport Utility 5.4.1 ("new"), second with Airport Utility 5.3.1 ("old"). Time Capsule with firmware 7.4.1.
Initial tests for connection Rate:
"New" average about 122
"Old" average about 232 (about twice the Rate)
Installed Airport Utility 5.4.1 on "old" iMac.
New tests for connection Rate:
Both averaging about 116
To me this suggests an effect of the "upgrade" to 5.4.1. But could this be the case? I'm not going to downgrade the firmware quite yet until I rule this and any interference issues out.

Very Poor Video Quality

I was trying to iChat with my daughter this afternoon and the video quality was horrible. She was pixelating large and small, trailing, etc. I think it may have something to do with the refresh rate. She has a new MacBook, which I assume is running 10.5.6. Any ideas?

Hi Defcom,
thanks to you man, finally my iChat Video is working. After fiddling around for several weeks and not finding the answer, I saw your recommendations for the Quicktime-streaming and the bandwide maximum, put it to work and now iChat is working.
Thanks to you man.
This leeves the question why such important information is nowhere to be found in the documentation of iChat. This is a serious omission in my opinion. Look at how many people have problems with iChat Video! And then such a simple solution, just somebody has to tell you.
Thanks alot again defcom.

[SOLVED] Very poor video frame rate after upgrade

I'm relatively new to Arch, having been a Slackware user for many years (since Slack 3.5), so please treat me gently!!
I installed Arch about a month ago from the network and had everything running well, including Firefox 4.0. Today when I started the PC and ran Firefox, I received a message recommending that I install Firefox 4.0.1. I duly downloaded the Arch package for FF 4.0.1, but it wouldn't run, complaining that it couldn't load XPCOM. I searched through the Arch forums and found a suggestion to run Pacman -Syu to upgrade the system. This upgraded around 140 packages, including quite a few Xorg ones.
Now I find that watching any sort of video in Xorg (e.g., The BBC weather forecast in Firefox or BBC Iplayer, or even glxgears), the frame rate particularly at full-screen is abysmal, dropping as low as around 2 (two!) frames per second. Glxgears manages around 9 frames per second. Before today's system upgrade, glxgears achieved exactly 60 frames per second at any screen size and BBC video was smooth at full-screen.
I'm guessing that the problem is somewhere in an upgraded Xorg package, but I'm completely in the dark as to where to start looking. There are no obvious problems reported in /var/log/Xorg.0.log. I could post the content of this file if required, but it's huge and would make an extremely long post.
Please could someone offer me some guidance on where to start looking for the problem and how to fix it. The hardware I'm running on is Asrock 890FX deluxe 3 motherboard, Phenom-II 955 CPU, Asus 1Gb Radeon HD5570 video card. 'uname -a' reports that the kernel is 2.6.38-ARCH.
I hope I've posted this in the right forum. If not, please advise accordingly!
Thanks in advance for any clues!
Gerald.

The files in your /etc/X11/xorg.conf.d folder are the standard ones, so they should not be the problem.
I've looked in your xorg.log, and while the problem is not clear immediately, you got several (WW) and (EE) messages in it.
[ 27.795] (WW) The directory "/usr/share/fonts/OTF/" does not exist.
[ 27.795] Entry deleted from font path.
[ 27.836] (WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/75dpi/".

these are safe to ignore
[ 27.837] (WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
without acpid installed, your monitor probably won't be blanked when you're system is inactive for a while, but otherwise this should not be a problems.
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
vesa and fbdev are intended as fallback options, it's better to install them.

Poor video from Leopard to Tiger

I've used iChat between an iMac and a MacBook almost daily for a year. At Christmas I upgraded the iMac to Leopard. iChat works, but I now get very poor video quality at the MacBook end. The connection doctor shows that typically my local bandwidth is around 200 - 300 kb/s but the other way is around 50 kb/s. Nothing changed in my router or any of the other networking hardware to the best of my knowledge.
Has anyone else experienced this? Any suggestions to improve the performance. Previously with Tiger at both ends the connection and video was usually fairly good and the connection rate more even.

Ralph: I have the exact same problem. Here is my output:

ZBook 17 g2 - poor DPC Latency performance when running from z Turbo Drive PCIe SSD

I'm setting up a new zBook 17 g2 and am getting very poor DPC latency performance (> 6000 us) when running from the PCIe SSD. I've re-installed the OS (Win 7 64 bit) on both the PCIe SSD and a SATA HDD and the DPC latency performance is fine when running from the HDD (50 - 100 us) but horrible when running from the PCIe SSD (> 6000 us). I've updated the BIOS and tried every combination of driver and component enabling/disabling I can think of. The DPC latency is extremely high from the initial Windows install with no drivers installed. Adding drivers seems to have no effect on the DPC latency. Before purchasing the laptop I found this review: http://www.notebookcheck.net/Review-HP-ZBook-17-E9X11AA-ABA-Workstation.106222.0.html where the DPC latency measurement (middle of the page) looks OK. Of course, this is the prior version of the laptop and I believe it does not have the PCIe SSD. Combining that with the fact that I get fine performance when running from the HDD I am led to believe that the PCIe SSD is the cause of the problem. Has anyone found a solution to this problem? As it stands right now my zBook is not usable for digital audio work when running from the PCIe SSD. But it cost me a lot of money so I'd sure like to use it...! Thanks, rgames

Hi mooktank, No solution yet but, as of about six weeks ago, HP at least acknowledged that it's a problem (finally). I reproduced it perfectly on another zBook 17 g2 and another PCIe SSD in the same laptop and HP was able to reproduce the problem as well. So the problem is clearly in the BIOS or with some driver related to the PCIe SSD. It could also be with the firmware in the drive, itself, but I can't find any other PCIe drives in the 60 mm form factor. So there's no way to see if a differnt type of drive would fix the problem. My suspicion is that it's related to the PCIe sleep states - those are known to cause exactly these types of problems because the drive takes quick "naps" to save power and there's a delay when it is told to wake back up. That delay causes a delay in the audio buffer that results in pops/crackles/stutters that would never be noticed doing other tasks like video editing or CAD work . So it's a problem specific to folks who need low-latency audio performance (very few apps require low latency audio - video editing, for example, uses huge buffers with relatively high latency). A lot of desktops offer a BIOS option to disable those sleep states but no such option exists in HP's BIOS for that laptop. In theory you can do it from within Windows but it doesn't have an effect on my system. That might be one of those options that Windows allows you to change but that actually has no effect. One workaround is to disable CPU throttling. That makes the CPU run at full speed all the time and, I believe, also disables the PCIe and other sleep states. When I disable CPU throttling, DPC latency goes back to normal. However, the CPU is then running full-speed all the time so your battery life basically goes to nothing and the laptop gets *very* hot. Clearly that is not necessary because the laptop runs fine from the SATA SSD. HP needs to fix the latency problem associated with the PCIe drive. The next logical step is to provide a BIOS update that provides a way to disable the PCIe sleep states without disabling CPU throttling, like on many desktop systems. The bad news is that HP tech support is not very technical, so it takes forever for them to figure out what I'm talking about. It took a couple months for them to start using the DPC Latency checker. Hopefully there will be a fix at some point... in the meantime, I hope that HP sends me a check for spending so much time educating their techs on how computers work. And for countless hours lost re-installing different OSes only to show that the performance is exactly the same as shown in the DPC Latency checker. rgames

Poor video playback with Windows XP

Hi all,
I am trying to play TV shows that bought from the ITMS (Xena & Star Trek remixed originals). I seem to be getting poor video playback performance. The video is briefly freezing and skipping. The frame rate is also not very good.
System specs:
2.6GHz P4 with hyperthreading enabled
2GB RAM
Matrox Parhelia 128 video card (latest drivers and firmware)
Soundblaster X-Fi Platinum
WinXP Pro SP2 + latest hotfixes
iTunes 7.2
I bought my first TV show after upgrading to iTunes 7.2 so I can't compare performance with v7.1 or earlier. I've tried playing the videos from a local IDE (D:, 60GB free out of 120GB) and from my 1TB Buffalo Terastation (RAID 5, 750GB). The performance is the same. The CPU activity varies from 75% to 95% CPU usage while playing the videos.
Even though my Matrox Parhelia is 3 years old it is still one of Matrox's top performance video cards and does excelent 2D and pretty good 3D.
Any help will be appreciated.
Thanks,
Steven

You're leaping to a conclusion that isn't supported by any facts. Just because you are having a problem is not an indictment of Safari 4. I'm having no trouble, nor are millions of other users, so that destroys your thesis. The problem is something that was a pre-existing condition on your Mac.
Did either of you Repair Disk Permission before and after installing it? If not, start with that. Do you have the most recent version of Flash installed? If not, download the Flash uninstaller from the Adobe web site, then the lastest Flash installer and run those, then restart Safari and test it on some video.

Video podcasts won't sync to iPhone

Got a confusing problem here, with a MacBook Pro (up to date on all software) and a new iPhone 3GS.
I can download and play video podcasts within iTunes on my Mac. However, they will not sync from iTunes to my iPhone, even after I use the "Create iPhone version" command and it spends ten minutes converting them. iTunes gives the error that the video cannot be played on my iPhone, so it's not going to transfer it.
Here's the confusing part: if I use iTunes on the iPhone itself (not on the Mac), I can download and play those very same video podcasts successfully. Huh? How come they work fine on my iPhone when downloaded directly to it, but not when downloaded via my Mac?
Any suggestions? FYI, here is one of the videos in question:
http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?i=56243345&id=2965 02584

I've been having the same problem: video podcasts contained in playlists are skipped over the the sync process. (These same video podcasts will sync fine if I choose something like "sync only the 5 most recent episodes of the selected podcasts." The trouble is, I've just started watching a long video podcast and would like to watch it from the beginning rather than from the end.
Any advice... short of deleting all but the desired episodes and then slowly re-downloading them as needed?

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.
