For some reason, they prevent sleep when drives are encrypted too and affects all disks, not just firewire. If they are unencrypted, they spin down when ejected immediately. One way to get round the problem with encrypted disks and may work with this issue is to manually set disk sleep to the lowest option of 1 minute. The option in system prefs I believe defaults this to 10 minutes, which is way too long to wait for a drive to spin down during a drive eject. Use the...
If you run the Blackmagic speed test, what is the rating you get for the 7200 rpm drive?https://itunes.apple.com/us/app/blackmagic-disk-speed-test/id425264550?mt=12Also, if you open the inspector window in Quicktime, what does it say is the bitrate for the video?You can also try using ProRes 4444, 422, 422LT and 422Proxy at 1080p and see how they run. I think 4444 will have trouble on a 7200 rpm drive but try it anyway.It depends on the program but when effects can be...
If you can login as root, can you try to mount the disk image using the terminal: hdiutil attach -autofsck /Users/username/username.sparsebundle Replace username with your actual home folder name. FileVault 1 sparse images can get corrupted during a system crash so it is possible that it won't be mountable.
It was Q4 for the dual-core chips:http://ark.intel.com/products/76348/Intel-Core-i5-4200M-Processor-3M-Cache-up-to-3_10-GHzI haven't seen many of those used. The i7 chips have been available for a while but they couldn't leave the entry i5 out of the update. There were a couple of laptops using the 5200M reviewed in December:http://www.notebookcheck.net/Toshiba-Satellite-C75-A-13P.107132.0.htmlhttp://www.notebookcheck.net/MSI-CR61-i5U45FHDW7.107948.0.html
It's both the decoding requirements and file sizes but file size tends to be the bigger bottleneck. Laptop hard drives are usually around 50MB/s so for a stream that needs 160MB/s, it will playback at 10fps or less. External drive manufacturers use uncompressed workflows to show off their drive performance:Their stats show nearly 160MB/s for 1080p and the Pegasus handles 6 streams.For video playback and basic video chopping, a dedicated GPU won't make a difference. For...
No, they are both uncompressed during playback. If the H.264 is decoded on the GPU, it would actually put more load on the GPU. The weak point is getting the data to it. The GPU is always rendering at 60 FPS for screen refreshes.You can see here an old Macbook Air with weak integrated graphics running 4K RED video no problem:If the RED video is decoded on the Air CPU, it chokes because the CPU isn't fast enough. Decoding it using the Red Rocket produces uncompressed...
The issue with the Mini would be the hard drive. The Blackmagic drive speed test shows which video quality is usable on the chosen drive:The PCIe SSD drives are very fast, it shows the formats and resolution at the bottom (uncompressed 4444 10-bit reads are 4th column):If Apple updates the Mini to use a PCIe SSD along with a standard HDD, the SSD will allow playback of high bitrate codecs no problem. Video memory could have been an issue before for 4K but this is likely...
The new one did ok with compiling:http://www.anandtech.com/show/7603/mac-pro-review-late-2013/5Firefox with 10 million lines of code compiled in just under 5.5 minutes. There's a chart of codebases here:http://www.crunchyfriday.com/wp-content/uploads/2013/11/1276_lines_of_code5.pngAndroid itself is listed as just over 10 million.Apple uses the same CPUs as their competition and are price competitive. The only problem is topping out at 12-cores at $6500 for CPU tasks where...
Yeah, Wall Street has only valued Apple at over 9x the value of HP (the largest PC manufacturer in the world). Why not 13x? Pitiful. Tim needs to be replaced with the CEO of HP in order to reach that lofty 1/9th value, then all the shareholders will be over the moon.
The access was from a device she's never used for her account before and from a different country. She mentioned she'd give all her things away to people so perhaps a family member got one of her smartphones.
