I am a security researcher and after hearing that "fixes" for the Meltdown and Spectre CPU vulnerabilities could reduce performance I installed Novabench to see if would help me investigate this. (You may see an uptick in downloads from other people thinking the same as me.) The product is easy to install and use, but I was surprised that every time I benchmark my test system the score increases, for no obvious reason. That makes me uncomfortable using this tool for research, but I freely acknowledge that performance testing is not my area of expertise, so could I be missing something? (BTW, if I decide to use Novabench in my work, for example, to produce an article on this topic for our blog (WeLiveSecurity.com) then I will be sure my company buys a commercial license.) Appreciate any light you can shed on this (excuse the pun - derived from your graphics test with the light hitting the storage shed). Stephen Cobb, CISSP
I've owned the Mac Pro 2013 for a year. Its the six-core model that came with 16GB RAM and 256GB SSD onboard. My experience with this machine has been frustrating from the beginning. Frankly, the 2007 Mac Book Pro 17" with 16GB OWC memory and a 1TB SSD feels peppier. That's unfortunate because I bought the Mac Pro to be my home workhorse. The problems started from the purchase. The Apple store sold me the LaCie Thunderbolt 4TB drive (still rotational). Migrating from the 17" Mac Pro, with 1TB, to a 256GB drive meant I had to pick and poke my way through installations. That caused lots of problems. So much for that new machine responsiveness. Key for me was that I couldn't even back up my iPhone 128GB to my home computer. I had to go find a Terminal Code to try to defer the backups to another external drive. That wasn't an Apple experience. Well, not the "It just works" experience which has been the purpose for owning a Mac. I just need to get work done fast! For the last year, I've experienced this balancing act of NOT ENOUGH. Not enough RAM even at 32GB now. Not enough Storage on board though I upgraded to the OWC Aura 1TB. There was simply no way to Work. Despite Apple's paradigm of designing and extremely fast (supposedly) Main computer that can run multiple monitors, drives etc, ironically Adobe didn't get the email and still wants to run only on the onboard SSD. After experiencing lousy performance running Creative Cloud on the LaCie, I installed on the local SSD. Better but not screaming. During the year I also got a QNAP TVS-863. Unfortunately just one month before QNAP released a Thunderbolt version. The bottom line is that Apple sold underprovisioned hardware as an entry level tool but which I'd argue was a glorified email reader with no guts to do run hard and fast. - $4000 Mac Pro, - $300 LaCie D2 Thunderbolt/ - $900 OWC Aura - $3500 QNAP Server and 28TB worth of disks To their credit when Apple Care realized one point of concern that the 16GB RAM, they replaced it with 32GB RAM to see if that would keep the Mac from creating a swap file. That has helped but the margin of 3-7GB is usually based on running one Adobe App. I've now asked both Adobe and Apple about the problems I've had with poor running performance and each blames the other and insists they don't talk to each other to seek the highest performance. I hope that was just poor customer service. The net effect of the failures of this machine is that my clients have at times experienced poor performance bottlenecks because I had to deal with dramatic slowdowns, had to reinstall System software several times and Adobe Software more than a few times. The Mac Pro 2013 has been a dismal failure in my opinion. It has not been the backbone of my office. Its been a ball and chain that is constantly demanding more RAM or a separate SSD Thunderbolt Raid. All of the hobbling around I've done has been due to Mac making this system so expensive that you have to be ready to fork out another $5000 to make it usable. Its an amazing idea to essentially make the entire office the virtual hardware enclosure instead of confining drives and peripherals to a box but its not going to work if all of the software wants to be nuzzled up close to the CPU bus and not at the other end of a thunderbolt tether. And it would also help if there were a central application that helped manage all of the Application Libraries to be stored on external drives: Mail, Photos, Music. So what's the story? Both Apple and Adobe seem to falling flat on their faces by layering their hardware and software solutions with Community driven layers to sell Cloudliness instead of focusing on maintaining their prowess as power suppliers to power producers. Both Apple and Adobe need to wake up. Faster PC's are available and millennials are not using Adobe as much as their predecessors. I'm not longer limited to owning a Mac Adobe product when I can as easily own a PC and get the Adobe software. I'd like to know if anyone else has had these problems and experiences and if a magic RAM/STORAGE/CPU combination has been successful. Mine's been shite.
Hoping for some good advice. My daughters MacBook Air got OJ spilled on keyboard and stopped working. Sent it back to BestBuy who said it needed a complete rebuild. When they returned the Mac it surprising started to work. I had reinstalled Office and it limped along. Keys are a little sticky but work. The issue is that it is very slow and I don't know if there are any utilities that can resolve or if a small amount of work is needed on hardware - I do not want to pay for a rebuild as it costs more than buying new. Below are my NovaBench results. Grateful for any advice you can offer.

I recently replaced two 2gb Kingston 1333 ram sticks with two 8 gb DDR3 1600 Crucial (Ballistix PC3-12800) sticks. I went into the BIOS and increased the memory to 800 Mhz (1600) and reran the Novabench. With the 4gb the score was 112 and 3560 mb/s. With the 16 gb the score was 194, but the speed was only 3425 mb/s, and that is after changing the bios. Why the lower speed?
