Looks 'normal' to me. Your boot sequence aught to continue regardless.

Beat me to it! :) Perhaps you could go a bit further, and explain in more detail your own setup in regards to multi-monitor? That is, assuming you have such mult-monitor setup. Presumably its all exactly the same as per the OP's Gaming 5 in post #1.

Its a Samsung 850 Evo in the cheapest possible ($10) usb 3.0 enclosure... I wouldn't be surprised if the little sata controller on it was only sata 2. [EDIT] It seems if I want to buy a new one, the best choice would be USB 3.1 Gen1 with 'USAP' signalling feature. Since SATA III is limited to...

and @ThePsyion @paulkol sorry nevermind. Is OK now. Its because had been testing on 'dd' command with /dev/disk which is very poor performance. Instead, /dev/rdisk is the correct block device to use in osx... So actually the USB 3.0 ports are all working fine. And at the full usb 3 speeds. No...

Sorry nevermind, problem solved. Because testing with 'dd' command on /dev/disk is very bad performance. Instead must use /dev/rdisk.... The USB 3.0 was working fine actually. Many thanks for joevt (on other thread), who pointed that out to me.

Horryay! Yes, it is this ^^. Your suspicion was correct. I was using '/dev/disk'. And that was the only reason for the reported slow speed. With your suggestion about trying rdisk instead, it works absolutely fine. 251 MB/sec for the SSD. And 38.4 MB/sec for the hard drive. # ssd...

OK thanks joevt, and @RehabMan for your other suggestions about testing USB 3.0 speed. I will try those when it becomes possible for me to do so. a) Yes I was wrong about the issue being related to hot-plugging USB on the Alpine Ridge. Have retested also with the USB device plugged in from...

Well that is good news. Nice to hear. I don't suppose you can share with me your clover folder to compare to my one? My USB still isn't working right. Many thanks.

Hello there! I have a very similar motherboard. Everything else is working, however unfortunately all of my USB 3.0 ports only working at the slower 2.0 speed. So it would really help to compare my EFI folder against your one. If its not too much trouble, can we do this? Please to email me a...

Hi there. Did you manage to get your USB 3.0 ports working at USB 3 speeds in the end? Because I'm experiencing the same exact issue, on a similar motherboard here (ga-z170x gaming 3).

Hi there, I also noticed this message today. Noticed similar messages here: https://pikeralpha.wordpress.com/2017/01/14/does-apple-load-microcode-for-the-igpu/ SSDT Stuff Loading.... .... ACPI: SSDT 0x00000000AED4F0000 6081E6 (v01 PwRef CpuPm 00003000 INTL 20120328) ACPI: SSDT...

Oh I'm very sorry. It was because it was 4:30am at that point and very tired, had been up for 22 hours. Please find attached again (i make sure this time!). Its got the ssd in it. Speed test here (of same session new again): Last login: Thu Mar 16 14:09:15 on ttys001 ga-z170x-g3:log janitor$...

zipb, the '2 weird port' are USR1 and USR2. Most likely from default iMac17,1 hardware profile (mac hardware specific), and definately nothing about the Thunderbolty. To get Thunderbolt 3 working (according to joevt say to me in a PM), you just need the latest sierra version 10.12.3. And to...

OK, now booted into ubuntu 16.04.1 live cd, and plugged back the 60GB hard drive into the adaptor, and then a USB 3.0 port. Here is the speed on linux: ubuntu@ubuntu:~$ sudo bash -l root@ubuntu:~# dd if=/dev/sde of=/dev/null bs=1m count=100 dd: invalid number: ‘1m’ root@ubuntu:~# dd if=/dev/sde...

Interesting... I test the speed in windows and its about 27MB/Sec. Which is still USB 2.0 Speeds. So I take out the 2.5 inch hdd and replace it with an ssd. Now says 180MB/sec in windows OK... And 20MB/Sec in OS X: ga-z170x-g3:log root# dd if=/dev/disk1 of=/dev/null bs=1m count=100 100+0...

OK Thanks! This ^ above sentence is very easy to understand. Perhaps you could add in your post #1 for other people to know that. OK so then I attach here all new latest Problem Reporting files. Plus in the Terminal Saved output it also include my DD speed test command and results 14MB/Sec...

Ah OK! I seen now, they were already included in my clover's config.plist, because I base that off somebody else's (who has slightly different motherboard). Right sorry. But that was actually my 'why?' question: What is the effect of ignoring the 15 port limit? That we cannot remove the config...

Uh sorry I didn't bother to check the 2nd monitor hot-plugging in that situation (when DVI is identified as 40,000 DP). But it certainly booted up into MacOS fine with DVI as the single monitor only. Didn't notice any (*obvious*) issue or anything strange during that brief login session.

@RehabMan, Sorry to be a nuicanse again here. My understanding is better now. Just can you please confirm these few things about the USB ports? It would help improve my understanding very much. Thank you. So I can't use FakePCIID_XHCIMux.kext. That is only for Z97 and earlier mobos. I read...

Oh sorry @RehabMan, I thought its limit of 15 *physical* USB ports. There are only 13 on this motherboard. That both HS + SS counted as 1 USB port. OK so I removed HS01, HS02, HS03, HS04, HS05, HS06, and HS09. While keeping only SS01, SS02, SS03, SS04, SS05, SS06 and SS09 for all these USB 3.0...
