OS X Mavericks 10.9.4 (Build 13E9) Seeded

Apple seeded OS X 10.9.4 (Build 13E9) to registered Mac developers, made available through their Software Update mechanism in the Mac App Store, as well as through the Mac Dev Center.

Other people can get the developer preview with help of this blog article.

Changes

The most interesting part is the addition of three new resources (plist) files for power management:

Mac-81E3E92DD6088272.plist / iMac15,1 (IGPU only)
Mac-42FD25EABCABB274.plist / iMac15,n (IGPU/GFX0/Apple display with id 0xAE03)
Mac-FA842E06C61E91C5.plist / iMac15,n (IGPU/GFX0/Apple Retina display with id 0xAE03)

This is based on the perf-bias value of 0x1 (highest performance) which happens to be the same as the current iMac14,n models – all other Mac models use 0x5 and 0xf. Unsurprisingly, of course, since Apple doesn’t want you to drain the battery flat in say two hours.

Update:

The EDID data for the GFX0 display is set to a screen size of 60 x 34 CM but the resolution data is blank.

Update-2:

I compared some of the data in OS X 10.9.3 with OS X 10.9.4 (Build 13E9) and found some additional changes. Some of which may indicate that the new iMac may have a Retina LCD. Which would be awesome.

System/Library/SystemProfiler/SPDisplayReporter.spreporter/Contents/Resources/English.lproj/Localizable.strings:

spdisplays_vram_shared = “VRAM (Dynamic, Max)”;
SystemProfiler_VRAMDynamicMax1536
spdisplays_retinaLCD = “Retina LCD”;
spdisplays_airplay = “AirPlay”;
spdisplays_airplaydisplay = “AirPlay Display”;
spdisplays_projector = “Projector”;
spdisplays_virtualdevice = “Virtual Device”;
spdisplays_captured = “Display Captured”;
spdisplays_donotdim = “Do Not Dim”;
spdisplays_stereo = “Stereo”;
spdisplays_1080p = “1920 x 1080 @ 60Hz (1080p)”;
spdisplays_1080i = “1920 x 1080 @ 60Hz (1080i)”;
spdisplays_720p = “1280 x 720 @ 60Hz (720p)”;
spdisplays_true480p = “704 x 480 60Hz (480p)”;
spdisplays_480p = “720 x 480 60Hz (480p)”;
spdisplays_480i = “704 x 480 60Hz (480i)”;
spdisplays_displayport_adapter_nonapple_dual-link_dvi = “Mini DisplayPort To Dual-Link DVI Adapter”;
spdisplays_displayport_adapter_nonapple_vga = “Mini DisplayPort To VGA Adapter”;
kHW_IntelIrisItem = “Intel Iris”;
kHW_NVidiaGeForceGTX750MItem = “NVIDIA GeForce GT 750M”;
kHW_AMDFireProD300Item = “AMD FirePro D300″;
kHW_AMDFireProD500Item = “AMD FirePro D500″;
kHW_AMDFireProD700Item = “AMD FirePro D700″;

System/Library/SystemProfiler/SPMemoryReporter.spreporter/Contents/Resources/English.lproj/Localizable.strings:

“is_memory_upgradeable” = “Upgradeable Memory”;
SystemProfiler_MemoryUpgradable
Update-3:

Apple uploaded a new version of OSXUpdCombo10.9.4.pkg (Build 13E9a) but all I could find out so far was that some of the installation scripts and SystemVersion.plist was touched – no changes were made to the mach_kernel, frameworks or kexts. It did also not show up as a new update in the App Store, so it is, apparently, not intended for people with Build 13E9 installed. It also won’t install over builds: 13A598, 13D65 and of course 13E9a.

Edit: I also added two small screenshots.

Update-4

Apple changed some of the data in OS X 10.10 Yosemite Developer Preview. They also added a new display override file: /System/Library/Displays/Overrides/DisplayVendorID-610/DisplayProductID-AE03 so guess what. One of the to-be-released iMac’s will have a Retina LCD. It’s the one with board-id: Mac-FA842E06C61E91C5 ;)

    • The data for the iMac15,1 could as well be used for a Macmini7,n I guess, and I was planning to have another look this morning, after my first cup of coffee, so who knows what else might be there to find ;)

  31. I saw those power management plists, but how were you able to tell that they were for iMac15? I couldn’t find that anywhere.

    • Hi Jason,

      I wrote a script called freqVectorEdit.sh to decode the ‘FrequencyVectors‘ data, which I used to compare the data with that of current iMac models. The only Mac models to use a pref-bias value of 1 (with some additional data). This value is used to program the lowest four bits of the IA32_ENERGY_PERF_BIAS MSR (0x1B0) with a value from 0 to 15.

      The values represent a sliding scale, where a value of 0 (the default reset value) corresponds to a hint preference for highest performance and a value of 15 corresponds to the maximum energy savings. A value of 7 roughly translates into a hint to balance performance with energy consumption – though Apple uses 5 instead.

      I also checked the changes to graphics power management, where ACPI device names like IGPU and GFX0 tells us what board-id will use the IGPU (only) and what board-ids both.

      Note: Only Haswell based Mac models use FrequencyVectors!

      I hope this helps you to understand what I did ;)

      • Wow, that’s fantastic. Such a great resource. I’ve been looking everywhere for Mac mini news so I’ll be digging over here on that too. Thanks.

  36. Does anyone have any clue what GPU the new iMac will have? I hope they stick to nvidia. As a 3D artist, nvidia is a must for me.
