sokinso Posted February 5, 2015 Share Posted February 5, 2015 Hi guys is there any way of upgrading from Mavericks to Yosemite without repartitioning and still using chameleon? Link to comment Share on other sites More sharing options...
Allan Posted February 5, 2015 Share Posted February 5, 2015 With Chameleon is not possible upgrade your OS X like a real Macs, only Clover can make this. Link to comment Share on other sites More sharing options...

Mine was like that too. It was because the BIOS was set to maintenance mode after I flashed the update. To exit this mode, I had to press some function key at boot - I don't remember which one, but it is prompted when you turn the laptop on. Link to comment Share on other sites More sharing options...
sokinso Posted February 5, 2015 Share Posted February 5, 2015 With Chameleon is not possible upgrade your OS X like a real Macs, only Clover can make this.So the only way is to go with clover and uefi modded bios and re-partition everything right?

Allan Posted February 5, 2015 Share Posted February 5, 2015 I managed upgrade here using UEFI mode, never tested using the Legacy mode. Is not necessary re-create your partitions layout, just download the OSX and follow the steps for upgrading. PS: Always make a backup of your files.

sokinso Posted February 5, 2015 Share Posted February 5, 2015 UEFI Clover if your HDD was partition with GPT from first you can start from here ------ after finish setup os x now we will format efi partition open terminal and type sudo -sthen type your password then type newfs_msdos -v EFI /dev/disk0s1then type mkdir /Volumes/EFImount_msdos /dev/disk0s1 /Volumes/EFInow you will see efi paratition on finder open it ----- now we will prepare your efi folder to put it on it download this EFI Folder and as on main guide we will do some changes according to your hardware if you have nvidia card don't change dsdt or config.plist if you have AMD card use this dsdt and config Have AMD.zip if you have only intel gfx card use this dsdt and config Have No nVidia.zip config.plist will be replaced on EFI/CLOVER DSDT.aml will be replaced on EFI/CLOVER/ACPI/patched and add your serial generated by chameleon wizard to config.plist under SMBIOS > SerialNumber also replace ssdt-4 of your CPU on EFI/CLOVER/ACPI/patched after finishing edit to efi folder copy it to EFI partitation and follow this steps as on main guide Go to System/Library/Extensions and delete AppleHDA.kext , AppleIntelSNBGraphicsFB.kext . Copy all kexts on Extensions folder on Post Install folder to System/Library/Extensions . If you will do customisations below do it before copying kexts to System/Library/Extensions . Now run Kext Utility . Setup HWSensors . -----now we need new flash memory format it to fat32 and put on it this efi folder now restart with the new flash memory connected to notebook and press f12 and choose UEFI from usb device you will get screen like this atxx.png choose icon marked by read on pic and add entry for clover then shutdown and remove usb device and turn on notebook you now should auto enter to clover guy choose os x to boot os x to boot windows shutdown and press f12 and choose hard disk drive you will boot windows ------ this guide just trial for whom need this urgently So since my hdd is partitioned in GUID partition table i can avoid repartitioning right? And follow the process from above since I don't have clover uefi but chimera? So the steps are: 1.pre-install 2.install/update Osx (without repartitioning) 3.post installation 4.the above steps for clover ? Link to comment Share on other sites More sharing options...
Allan Posted February 5, 2015 Share Posted February 5, 2015 Yes with GUID mode is possible, but in UEFI mode enabled. Link to comment Share on other sites More sharing options...
sokinso Posted February 5, 2015 Share Posted February 5, 2015 Yes with GUID mode is possible, but in UEFI mode enabled.What do you mean in "uefi mode"?(the installation of the latest modded bios that unlocks uefi?)The steps i wrote aren't the right ones?

sokinso Posted February 5, 2015 Share Posted February 5, 2015 Update to Yosemite 10.10.2 successful. I was on mavericks 10.9.2 dual boot chameleon with win 7 and at last I decided to update.Here what I did 1.followed the pre-installation steps and video 2.booted with usb erased the old mavericks partition and installed 3.followed the post installation steps 4.DONE Simple as that. Clover seems nice and everything works great.(sleep, wifi atheros card, sound, dual boot with win 7 etc) Thank you all for this very helpful thread let's keep it that way! 2 Link to comment Share on other sites More sharing options...
