Our Computer Repair Services

“Took my MacBook Pro to fix the audio jack. They weren’t able to fix it without a new part. I did not wish to purchase the new part so they put it back together for me at no cost even though I expected to pay for the labour spent taking it apart. Thats stand up customer service. I will recommend to all my friends and family.”

He fixed the problem quite quickly and now it works as good as new. Great service at an affordable price. I will definitely be back for any future computer issues!”

I did not even call just showed up and Anthony greeted me and accepted challenge. His patience and experience was amazing. He fixed my problem and even was willing to help me upgrade. I have NEVER had such an experience as positive as I did today with JTG SERVICES….Anthony you rock !!!!! I will recommend this company to everyone who has computer issues…..especially your Mac.Cheers Carol”

“As a software developer I also do a lot of my own laptop repairs. However there are some repairs that are just too unnerving for me to do myself. When my Macbook Air became water damaged I had to draw the line.In all my years working with computers I can honestly say I have NEVER met anyone with knowledge and insight a great as John’s. He just seems to know exactly what the problem is and he knows how to fix it faster and cheaper than anyone I’ve ever met.John is a computer Ninja within an elite network of computer ninjas. If he can’t fix it someone within his network can. I will never take my computers anywhere else. This man is unreal.”

“Great service. This company is excellent at what they do. From replacing a disc drive to a macbook keyboard, they are always great, reasonably priced and quick to get things done. I would recommend this company to any other mac user that doesn’t want to go all the way to the genius bar or pay an arm and a leg for apple care. Great people!”

“This location provided me with excellent customer service! I was having troubles with my macbook, it wasn’t turning on or charging. After bringing it by, John was able to get it fixed, running 100% and back to me within the same day. I needed a new battery and they did the replacement at a great price. I would recommend this service to anyone with any electronics troubles.Fast, great service, and affordable!”

“John did a excellent job fixing my MacBook Pro. He even repaired my charger and took the time to help me solve some issues. Very helpful!!”

“I reached out to John after he was recommended to me from someone on a Niagara Advice Page. From the initial contact I felt I was in the best of hands. John was able to assist with a recovery of lost files & pictures after my Macbook decided to do a software update. Throughout the whole process, John was available through text message to alleviate all my stresses with the thoughts of losing years of memories. Would not go anywhere else from here on out and will always be referring him to friends and colleagues. KUDOS TO YOU & YOUR TEAM JOHN!!!”

“JTG Systems agreed to take a look at my mid 2012 Macbook as I had been having some issues. Upon return, I can say they did a fantastic job cleaning it. It has never ran better! I will definitely return for any and all computer needs in the future.”

“Completely fixed my MacBook Pro’s booting issues that the Apple agent couldn’t fix, and also fixed the insane overheating problems that I was facing, all under 2 hours while having great conversations with me! I can’t explain how grateful I am to John. The amount of money and the time that I’ve saved is just unbelievable. Thank you so much for the fantastic service! HIGHLY recommend him to anyone!”

“Very knowledgeable, honest & friendly !Tony answered any questions I had and provided very detailed answers and took the time to explain. I had brought in a desktop which I thought had a virus but did not… he took the time to tweak and repair a couple of things to make it run better. I could not have asked for better service ! While I waited !!! It was at very reasonable price . If I could rate more than 5 stars I would. I will certainly be recommening John & Tony at JTG Systems to all my friends and Family!!”

“Met with John last week due to my wife MacBook 12″ logic board failing. He took the time to look over it for many hours and determined the only repair was to replace it. He didn’t charge me a single dollar for his time and if I decide to go through with the repair I will definitely be bringing it back to him. very knowledgeable and friendly!”

“AMAZING! Saved all my data after a coffee accident ruined my MacBook ! I would recommend JTG to anyone with Mac problems, amazing to work with and doesn’t try to rip you off!”

“I had a wonderful experience. My computer (a Mac) was infected by a virus – one text to John, a prompt reply and an invitation to drop it off “anytime”. When he learned that I live in Port Colborne he fixed it immediately, charged me a very fair price and had it back up and running and in my hands within an hour and a half!!! Amazing customer service!! Thanks John – you will definitely be recommended to others by me and if I am ever in need of service again I will be in touch!”

“I HIGHLY recommend JTG Systems! John was extremely helpful in assuring me that my old Mac was an affordable, fairly simple fix. When another local computer repair business told me it was a lost cause, I almost gave up on it. He replaced my hard drive, added more RAM, updated it and explained everything he was doing in a way that I (a not so tech-savvy person) could understand. In just a couple hours, my computer was ready to be picked up and he even lent me a cable to connect my old hard drive to the computer, and move over old files. I’ll definitely be calling JTG for any of my computer needs from now on. Thanks again, John !”

“John looked at my Mac laptop, ran a test and was able to diagnose the problem within a few minutes. He had the part I needed and he was able to fix my Mac on the spot which was amazing!”

“My MAC was in a terrible state, it kept shutting down at 70% and I had so many ads popping up at the corner of my screen every time I log on :(. I researched and heard this place was open for 24 hours and heard amazing reviews about it. A good friend of mine had water spilled on her computer and she had to hand in her lab report in a couple days so she was freaking out. They fixed her computer in less than 24 hours and she was soooo happy! I wanted to give it a try so I came in on Wednesday, explained the problem to the worker and he explained what he was going to do to fix it…I think I gave them the wrong number because I had to call them the next day to see if everything was fixed…He said that everything was good and I could pick it up! It’s been a week now and I’m soooo happy that my MAC does not shut down randomly during meetings and live lectures, and I’m sooo glad that when I log in to my MAC, I don’t see random ads popping up! Thank you JTG systems for fixing my MAC :)! I’m very happy that it took them less than 24 hours to fix it and they were very professional with their work!”

“Mac was fixed within 30 minutes! great job!”

“I have a MacBook Air that is only a year old and used for Word or regular websites. My charging port stopped working so I went to BestBuy, they quoted me $300-$900 to fix or backup my information for $100+tax. I walked out feeling stuck and hopeless. I decided to call someone who specializes in Mac and isn’t “corporate”.Called JTG systems. Came in the next day, charge port was slightly moved and he put it back in place. Was very understanding and informative! 10 seconds and my laptop was working again! He then added virus protection programs to remove a current virus causing popups and also showed me tricks I didn’t know about my Mac. Ten out of ten would recommend. Forever customer now.”

“Took my MacBook Pro to Jumpplus only to have them tell me my computer required a $900 repair. Would not pay that so I checked around until I found JTG systems. Very honest and helpful people. Had my laptop fixed and useable within an hour. It was amazing how a $900 repair turned into a $60 one. Thanks again to John and the guys. Definately would recommend and will be going back!”

We have a 2009 Mac Book Pro. John took a look at it and immediately came up with a recommendation. John also understood that it would be difficult to be without our computer for a number of days so he had it back to us within 24 hours. John is extremely professional, knowledgeable and accessible.

“Excellent experience working with John. I called him on a Saturday expecting to have to leave a message and thought I’d have to drop my MacBook off the next week. Instead, he answered the phone and told me to bring it in right away. Dropped it off a few minutes later and John said he would get it done by the end of the day! Apple could not help me with their own machine, but John did, and he did it fast! I had been waiting for over a month for Apple. My MacBook has the weird “C” style USB ports, and I forgot to bring the adapter. John even offered to come and get it from my house in order to get the job done! My advice? Support your local businesses, especially the ones that provide a high level of customer care. I hope to never have computer problems ever again, so I’ll never have to go back, but who are we kidding? It’s going to happen, and when it does, I know where I’m taking my computer! John goes above and beyond to serve his customers. Highly recommend JTG Systems!”

They were both extremely satisfied with their service and the price for their repair.

Saved me from having to buy a new charger for just 10 days! Saved my vacation! Thanks JTG systems, I will return and continue to refer my friends!”

Very knowledgable and extremely helpful. Will recommend to anybody and will definitely comeback for any computer problems. A+++”

“**************HIGHLY RECOMMENDED*************I brought in my old Mac to APPLE STORE and they won’t change the battery cuz it’s “too old.”Thank God I googled “computer repair in niagara” and JTG staff replied within minutes, directed me to the Amazon link to order the battery and bring it to them to install. (VERY HELPFUL, thank you)When I brought in the battery and the Mac, the staff were all friendly, welcoming and very professional. The location is easy to find with free parking and close to Tim Hortons and Dairy Queen.The battery literally was installed in less than 5 minutes and they took the time to explain recalibration with me. (I appreciate that, thank you.)The staff mentioned a hard drive update would make the Mac go so much faster. It was only $100 and included an external hard drive. This installation only took an hour and it was no problem waiting since the mall is so close.The staff are kind and extremely efficient.I highly recommend everyone to bring their PC, MAC, and other devices into JTG.You guys are family now. Thank you for taking care of everything. It really took a weight off me.Sincerely,Laine LePoidvin”
