  1. Chameleon doesn't require UEFI, so my whole setup is in legacy mode.
  2. Well, Mark, I don't really have enough time to explain detailedly but I do have OS X and Windows working toghether without UEFI (legacy mode) on my XPS 15. As long as the bootloader sits on the internal drive, it will be able to boot the system installed on the caddy just fine. On my particular setup I do have OS X Yosemite installed on the SSD placed inside the caddy (couldn't bring myself to open the whole thing yet - I quite hate dealing with hardware) and Windows 8.1 installed on the HDD placed inside the laptop. My bootloader (Chameleon, btw) loads from the HDD and then points either to OS X on the SSD or to Windows within the HDD itself. The system is running just fine and the only thing that broke compared to Mavericks are the brightness keys (you can still use a small C program called screenbrightness - Google it - or OS X's ordinary control panel to control it, though). The necessary kexts and other files used to disable nVidia's GPU and get other parts of the system working can be found whithin this topic. The only kext that I needed to modify in order to get it working was the one responsible for the ALC665 audio controller (you can find how to do it here, on Insanely Mac. There's a topic somewhere).
  3. I did Luc, but on a L502X. As our notebooks are kinda of brothers, I bet I can share my experience. What do you want to know?
  4. I updated to 10.9.1 and bloody hell, it is so much better! The machine feels so faster and there are so many improvement hackintosh wise that I can only think that I must have screwed up with 10.8.3 installation. My visible improvements: 25 extra minutes of battery life with video (for nearly 3:40). 45 extra minutes of battery life with wifi (for nearly 6 hours). The system feels much snappier. Benchmarks are the same, but programs open faster and it boots on 1/3 of the time of ML. My audio is crisper, won't gets distorted at higher volumes as it was on ML. My screen can get as bright as in Windows (On ML the max was always a bit dim). My fan turns off when the CPU is cool - I could almost cry for this one. Was so annoying having it on all the time on ML. UI animations feels more fluid. Time Machine is doing it's mojo in less time. Can't precise how much. I'm properly getting S states (Enabling them with a SSDT caused a kernel panic on ML). HWInfo not display more information than before (Fan RPM). I had some pesky lags UI wise (as having the system hiccuping when accessing the menu 'Share' in finder), they are all gone. The reboot bug is gone. - I couldn't be happier.
  5. Wow... t65902 just convinced me about Maverick's prowess. I'll try it as soon as my new SSD arrives from China. - By doing so, I'll be free to use Clover instead of Chameleon. I have high expectations on this. - I enabled retina and tried 540p HiDpi. Things looks absolutely great, indeed. But everything got so absurdly big that I can't really use the laptop this way. Apple's + Safari's toolbars alone are munching pretty much 1/4 of the screen.
  6. Nothing clearly different in performance, power consumption or heat?
  7. Thank you, I'll see what can I do about it. When using it on a table to type the noise is a non issue, but when watching video it becomes quite annoying. Right now I'm thinking of going Mavericks on a SSD to see how it behaves. Loudness apart, my focus is snappiness and battery life. - Perhaps it's time to open it and do some modding too. Repaste the CPU, clean the blower and get rid of the dust filter. - One nice thing about our notebook is using a modded bios that undervolts the GPU to 0.83v. I used to have GPU temperatures on the upper 90's gaming on Windows, now it stays on lower 80's. No artefacts or whatsoever. Absolutely worth it.
  8. Yes, I'm using a modded bios that fixes OS X sleep, include a newer CPU microcode, native speedstep and also undervolt the GPU to 0.83v so it runs cooler when gaming on Windows. Also, this bios unlocks a handful of options on the setup. - I have a 2450M i5 on a L502X (XPS 15 R2 or 2011). - I will answer my questions myself as It may be useful for other L502X owners looking for a Hackintosh. First, I didn't go for Mavericks after all, prefering Mountain Lion as it is better documented in the Hackintosh community. I have no regrets. Mavericks is nice, but it's still a bit glitched. So 1) How the L502X is performing on ML? Overally it feels fast. Despise using the Intel HD3000, light gaming as League of Legends and World of Warcraft is more than possible on low settings, native resolution. Sometimes the system do hiccup and it can suffer from intense IO usage scenarios: My advice is get a SSD. I feel that ML is doing better than Windows 8.1 on my machine, specially for things like writing (or coding), browsing, listening to music... basic stuff, basically. The apps do open faster on my machine. But, it could be buttery smooth using a SSD. My CPU is rarely stressed on a daily usage, but the slow 5400RPM HD that Dell included on the L502X is taken to it's limits easily. One sort of a Easter egg that I found on Mountain Lion was video reproduction! I rented a bluray movie to watch with my GF and went to watch it days before installing ML. Unfortunately, we couldn't finish the movie that night. So I installed OS X 10.8.3 and downloaded VLC in the days between seeing her again. When we opened the movie, we both agreed 'Wow! Isn't the image a lot better?'. I have barely any knowledge on video reproduction so I can't say why, but my movie appeared a lot more 'HD', it is... sharper and clearer in Mountain Lion compared to Windows. I used VLC on both machines. I don't really know why. Perhaps it's the QE execution that VLC uses on ML, perhaps it's how the system treat graphics overally (as colour profiles and rendering schemes), and I say that because I feel that web and document browsing is a bit clearer on ML too. The downside of Mountain Lion is that albeit my processor isn't any hotter compared to Windows, the fan is audible louder. I'm currently working on this issue, that I found particularly annoying. 2) I have the 9 cell L502X. How's our battery doing? After installing proper speedstep management and disabling the nVidia discrete GPU, can we achieve livable battery life with OS X? Mavericks 'under the hood' improvements that gave a lil' extra juice to actual Mac hardware did benefit us? After fine tuning, installing speedstep, getting rid of the (on my case) useless turbo boost and some bios modifications, I'm getting nearly 5:30~5:40 of web browsing with the screen dimmed. That's a pretty good value, since it's a hackintosh and my 9 cell battery is quite weary by 18 months of heavy, daily usage. Battery when reproducing video isn't anything to write home, though. I'm getting 3:40 out a 720p AAC MKV encoded video. I'm still considering Mavericks on another HD so I can check how it fares when it comes to battery life. Many Apple-hardware OS X users saw a healthy increase in battery with Mavericks, I can't but wonder that I might benefit from that on my Hackintosh too. Yet again, a SSD instead of the mechanical HD would help a lot here. A bloke on notebookreview's forum saw a battery increase of one hour with a SSD. 3) Is dual boot possible somehow in one partitioned HD? In a single word: Yes, it is. And it was pretty easy to do it. I just patched Mountain Lion installer so it could be installed on a MBR partitioned HD, created a partition for OS X using Windows's dskmgmt.msc service and voilá, installed. Works like a charm. I didn't even had to lose my Windows files, which I can access from OS X now using Tuxera NTFS. However, I found some downsides using this. First: MBR won't partition a disk in more than 4 partitions whilst GUID is pretty much (piratically) limitless on this area. This hurts my Hackintosh as I have one partition to Windows, another to Windows Recovery (which I unfortunately need), one to OS X and one small one from Dell that I can't delete without loosing my data. Because of this, I couldn't create a 50GB partition I was wanting to use Time Machine. As converting to GUID requires erasing data, I'll have to live without it for a while. Second: UEFI won't do well with MBR. If I wanted to use CLOVER instead of Chameleon, I'd had to go GUID. Third: I can't really say whether it was MBR's fault or not, but I had a hard time getting the bootloader working on this scheme.
  9. I bet no one come here anymore. I have ML 10.8.3 fully working on my L502X. The only thing that still bother me a bit is that even with the nVidia card properly disabled and temperatures nearly identical to Windows, my machine still is considerably more noisy on OS X. Don't really know why...
  10. Hello, Hou are you doing? I've been reading this topic silently since I started considering a Hackintosh on my XPS 15. After some consideration and trials on OS X, I think it's quite time to give it a shot. However, before starting I have a set of questions that weren't settled upon reading the thread, so I was wondering if any of the users that contributed to this topic would be so kind and help me solving my doubts. I'd be very thankful if anyone answered those questions: 1) How is L502X performing on Mavericks? I have a painfuly slow 5400RPM hard drive and Windows is quite ok with performance, albeit intense IO situations (as in hi-speed torrent) being more than enough to put my system to the ground. Will the performance penalty of a Hackintosh make this situation worse? 2) I have the 9 cell L502X. How's our battery doing? After installing proper speedstep management and disabling the nVidia discrete GPU, can we achieve livable battery life with OS X? Mavericks 'under the hood' improvements that gave a lil' extra juice to actual Mac hardware did benefit us? 3) Is dual boot possible somehow in one partitioned HD? Thank you very much. Merry Christmas and Happy Holidays!
