While there are plenty of tips and tricks for what to do within Minecraft, not many people talk about how to boost performance. Classic Minecraft Java Edition can get bogged down by shaders and modpacks that expand and update the game beyond its original scope. Fortunately, you can always just allocate more RAM to it so that performance doesn't suffer too much -- as long as you have enough RAM, that is.
Here's how to allocate more RAM to Minecraft, regardless of how much you have in your system.
Note: Minecraft Bedrock Edition can take advantage of more RAM without you having to manually adjust anything. This tweak is for the Java Edition of Minecraft only.
The Java version of Minecraft has (by modern standards) a relatively small quantity of allocated RAM, and without you giving it access to more through the launcher, it can't go beyond that. That leads to poor performance or crashes when the memory runs out. Here's how to allocate more.
Step 1: Open the Minecraft launcher and then select the Installations tab.
Step 2: Find the profile that you want to change memory allocation for, and select the three-dot menu icon.
Step 3: Select the More options button under the "Resolution" subheading.
Step 4: Scroll down to "JVM Arguments" and look for the "-Xmx2G" parameter.
Step 5: Select the text and use your keyboard to change "-Xmx2G" to "-Xmx8G". That will allocate 8GB of RAM to the Java launcher, which for most installations should be enough. That said, you can theoretically change it to any quantity divisible by 2 that is under your total RAM quantity.
Step 6: When you've set it to the quantity you want, close down those options menus and run Minecraft again to see how it performs.
If you want to see how much memory you have left over, while playing, press and hold the F3 function key. It will display how much memory you have to spare and whether you might need to allocate more.
If you're using the CurseForge launcher, you can allocate more RAM in a similar but slightly different way.
Step 1: Open the CurseForge app, and select the Settings cog in the bottom-left corner.
Step 2: Under the "Game Specific" subheading, select Minecraft.
Step 3: Scroll down to find the Java Settings category. Use your mouse to adjust the slider bar to allocate more RAM to the game. Again, 8GB should be enough for more installations, but you can go more or less depending on your hardware and specific needs.
Speech-to-text apps have flooded the App Store, making it easier than ever to type on our Macs with just our voice. I have previously covered one such app called TypeWhisper. However, there has been a dearth of good text-to-speech models, and most of the good ones are locked behind a subscription.
Ollama, an open-source app that lets you run local AI models on your computer, wants to change that. It works on macOS, Windows, and Linux, and your prompts are never stored or used for training.
Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.
How can ORISA bring deleted AI conversations back?
Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind.
The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).
