![]() ![]() Od failed with 2 proto=ntlmv1-with-v2-session It appears that there is a Console error generated on the Mac at the same time as the Windows machine tries to connect. No amount of credential-checking/switching seems to work. Logon failure: unknown username or password OS X The Windows machine generates this error. I can though WinSCP from my XP to the macbook using the same login credentialsīut I just can not get past this XP to macbook network access – I can however login from the macbook to the XP machines network drives and folders.ĭoes anybody have any solutions to this as I have come up stuck here The error was logon failure: unknown username or password reappearing again and again after trying to login. a login prompt and password appears but when I put in the user and password, the login re-appears but first with my XP machine user name back slash and the macbook user with password. Then type the path to the macbook folder. I can see them and login to them via the Win 7 machines network icon, but I can not see any of the mac folders ( or drive ) within XP … With upgrades you do get the odd thing going wrong but I have managed t resolve all but one problem in that I can no longer see any of the macbook-shared folders within the XP network icon. The macbook up and till recently had Mavericks 10.9.5 OS X, a few days ago I upgraded the macbook to OS X Yosemite. That fits with the issue being related to the primary SATA port.I have a combination of Win7 - XP & Apple macbook machines, running on my windows network. In contrast to my MacBook Pro, the update finished without problems on the iMac. ![]() Incidentally, I also have a late 2009 iMac where the original hard drive has been swapped out (drive failure - not even the same manufacturer) and an SSD occupies the optical drive bay. Afterward, I put the SSD back in and installed Hugh Sierra without any problems - as the firmware update had already been completed, there no longer seemed to be the system check that had tripped me up previously. The installation with the original HDD completed without any problems, including the firmware update. Luckily I kept the original hard drive around, and after trying the newest installer and rebooting into safe mode several times without any joy, I just took a screwdriver and put the old HDD back in temporarily (there are good guides on ). Turns out it was the aftermarket SSD I had installed pretty much as soon as I bought it. Had the same problem on a MacBook Pro 17” (Mid-2010). If that is the case, it probably can be fixed within $20 to get a replacement. It's said that, most of time, it is the hard drive cable which is out of order, instead of the chipset. So, you might have to get the primary SATA port work and connect your disk to it. That means the upgrade process was interrupted. ![]() The firmware upgrade process only recognize the ESP (EFI System Partition) of primary internal drive. The root cause of the failure at point A, in your case, is no internal drive in main bay. Hence, it reports "An error occurred while verifying firmware". As a result, the installer find out that your firmware is NOT a latest version still. It double checks the version of firmware to make sure it was updated successfully in previous process (namely point A). ![]() (marked as point A)Īfter the upgrade process (regardless success or fail), the installer continues. Then restart automatically and trigger the firmware upgrade process. The easy fix is to verify your backup and then erase the volume and run the installer against a blank / erased main storage drive.īecause the APFS requires support from a new version firmware, your mac's firmware will have to be updated to the latest version during the installation of High Sierra.Īfter the first restart, the installer prepares the latest version firmware which suitable for your mac model onto EFI system partition of your main disk with bless command. Apple has introduced a new file system APFS in High Sierra. ![]()
