Eat definition is - to take in through the mouth as food: ingest, chew, and swallow in turn. How to use eat in a sentence. The family of Macintosh operating systems developed by Apple Inc. Includes the graphical user interface-based operating systems it has designed for use with its Macintosh series of personal computers since 1984, as well as the related system software it once created for compatible third-party systems. In 1984, Apple debuted the operating system that is now known as the 'Classic' Mac OS with its release of the original Macintosh System Software. The system, rebranded 'Mac OS. Mac OS was the original operating system for Macs that was replaced by the current Mac OS X. Mac OS had been Apple’s primary OS from 1984 all the way to 1999 when Apple released Mac OS X Server 1.0 that was designed for server use.

WHAT IS MAC (MYCOBACTERIUM AVIUM COMPLEX) AND HOW IS IT DIAGNOSED AND TREATED?
- Formerly known as “atypical mycobacteria”, “atypical TB”, or “atypical AFB” and currently as “nontuberculous mycobacteria” or “NTM”. NTM includes all types or species of mycobacteria (including MAC) other than the germ of tuberculosis (TB).
- Related to Mycobacterium tuberculosis (Mtb) but it is not TB (tuberculosis).
- NTM includes a number of different species, but the most common one causing chronic lung disease is MAC.
- MAC is not spread person to person like Mtb. MAC is not contagious.
- MAC lung disease seen in HIV negative (non-AIDS) patients is a chronic lung infection and early-on is often misdiagnosed as chronic bronchitis or recurrent pneumonia.
- MAC Lung Disease is acquired from the environment (soil, air, natural waters, tap water, etc.)
- Scientists and physicians who have studied MAC believe people who develop MAC lung disease become infected because of a defect in the structure or function of their lungs (especially a disease called bronchiectasis) or in their immune systems.
- Damaged lung tissue can result from previous TB, heavy smoking, and a breathing tube disease called bronchiectasis.
- Bronchiectasis is a breathing tube (bronchial) disorder characterized by excessive mucus production, cough, and susceptibility to certain infections such as MAC or infection caused by bacteria such as Pseudomonas aeruginosa.
- Disease in men commonly relates to smoking while disease in women (non-smoking) usually relates to bronchiectasis.
- The average age of patients with MAC lung disease in men is 55 years and 67 years in women.
- Men are more likely to have cavitary MAC (holes in their lungs). Women are more likely to have non-cavitary, nodular MAC.
- Diagnosis of MAC lung disease usually requires:
- Medical history with records of symptoms:
- Cough, sputum production, shortness of breath
- Loss of appetite (anorexia is the medical term) weight loss
- Severe fatigue or tiredness with inability to perform daily tasks
- Rarely coughing up blood (hemoptysis is the medical term)
- Fever, night sweats
- Chest x-ray (a picture of your lungs internally)
- High resolution CT scan (HRCT) (similar to an x-ray but a more detailed picture)
- Sputum culture – several sputum cultures are usually performed. Your specimen coughed from your lungs is examined under a microscope (AFB smear) and also placed on special media to grow mycobacteria (AFB culture).
- Bronchoscopy – may be necessary in some cases (especially if you can not cough up sputum) but not all, and involves putting a tube down into your lungs to obtain specimens for culture.
TREATMENT OF MAC LUNG DISEASE REQUIRES A MULTI-DRUG REGIMEN (MORE THAN ONE DRUG).
- MAC is resistant to ordinary antibiotics.
- Combination of 3 drugs (all FDA approved)/dosages are based upon your clinical history, age, weight, and symptoms.
- Clarithromycin (Biaxin) or Azithromycin (Zithromax)
- Rifampin (Rifadin) or Rifabutin (Mycobutin)
- Ethambutol (Myambutol)
- The combination of medicines is given until no more MAC germs can be grown by culture of your sputum for 1 year. Average treatment period is about 15-18 months.
- Monthly sputum cultures are performed while you are on therapy and periodically when you finish your therapy to be sure your MAC is gone.
- The 3-drug treatment may be given 3 times weekly (preferably Monday-Wednesday-Friday) or daily.
- Data from previous treatment trials tells us that most patients (approximately two-thirds) who have no previous treatment of their MAC and who can tolerate the appropriate medicines will get better and be “cured” of their MAC lung disease.
- Patients who have failed a prior drug regimen of > 6 months for their MAC are more likely to fail the standard drug regimen (almost 50%).
- Patients who take the 3-drug regimen for less than 1 year with negative cultures are more likely to relapse with disease with their same MAC strain.
- Patients who fail therapy after taking the 3 medicines are usually required to take additional medicines. Injectables which may be useful include:
- Streptomycin or Amikacin
- Amikacin can also be given by inhalation (aerosolized) and is less toxic when given in this manner.
- Monthly laboratory blood tests that include a complete blood count and comprehensive metabolic panel (CBC and CMP) to check for possible damage to blood cells, kidneys, and liver.
- Most common potential side effects/complications of medicines:
- Clarithromycin : Loss of appetite, diarrhea, nausea, abdominal pain, abnormal liver function tests (blood tests), bitter taste, mild allergic rash.
- Azithromycin : Diarrhea, nausea, abdominal pain, abnormal liver function tests (blood tests), decreased hearing, tinnitus (sounds in ears).
- Rifampin : Nausea, vomiting, liver damage, decreased platelets (cells which clot blood), body secretions (urine primarily) are orange/red.
- Rifabutin : Nausea, vomiting, decreased platelets, decreased white blood cells (cells that fight infection), eye pain (uveitis), diffuse muscle and joint aches, skin pigmentation (yellow).
- Ethambutol : Decrease in vision (especially color vision), blurriness.
- Streptomycin : Kidney damage, sounds in ears (tinnitus), hearing loss, poor balance, numbness, tingling, muscle damage, fever, headache.
- Amikacin : Kidney damage, tinnitus, hearing loss, poor balance.
If you experience these or other additional problems, you should discuss them with your physician. - Amikacin by inhalation (aerosolization) decreases toxicity to above adverse events.
Provide a list of your current medicines to your physician so he can determine any possible contra-indications.
PULMONARY FUNCTION TESTING
What is a pulmonary function test?
Pulmonary function testing is a way to measure your breathing capacity and, therefore is an objective measure of how well you are breathing. There are several types of breathing tests that can be done during pulmonary function testing including spirometry, lung volumes and diffusing capacity. A technician will explain what you need to do during each test and will coach you during the tests to help you give a good effort. All breathing tests require more than one measurement so that you will be asked to make more than one effort for each test. Spirometry is the most commonly performed breathing test. It requires you to take in as deep a breath as possible and then blow out the air in your lungs as forcefully and fully as possible. Spirometry, therefore, measures how much air you breathe in and out and how fast you breathe air in and out. Spirometry is frequently performed at baseline and then after you have inhaled a bronchial dilating drug (breathing medicine) to evaluate the effect of medication on your breathing function. As with all pulmonary function tests, it is very important that you make a maximal effort to insure accurate assessment of your breathing function. Lung volumes are performed while you are sitting in a small chamber called a plethysmograph (or body box) and provide further information about how much air you breathe in and out. You will be asked to perform different breathing techniques such as blowing into a tube while in the chamber. Lung volumes are usually not performed unless there are abnormalities found on spirometry. The diffusing capacity is one measure of how well your lungs move oxygen from the lungs into the blood. The results of pulmonary function testing can tell you and your doctor how much your lungs have been affected by a disease process and help determine if specific therapy can be of benefit to you. They can also be useful for evaluating the effects of a disease or treatment over time. You will be given specific instructions about what to do with your own breathing medications when the breathing tests are scheduled. Pulmonary function testing usually takes between ½ to 1 ½ hour to complete, depending on how many of the pulmonary function tests you are asked to complete.

Which Mac operating system is the best is a topic of numerous debates among Apple fans.
Since the mission of this blog is to refute myths and legends around Macs, it’s time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.
The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2021 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.
How to Tell Which macOS You Are Running
To find out which macOS is currently running on your Mac, follow these steps:
- Click on Apple logo in the top left corner of the menubar
- In the dropdown click on the first item: About This Mac
- The first line in the Overview tab is the name of the current OS.
What Version of OS Can My Mac Run?
Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations.
For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.
Check below to know exactly what version of OS your Mac can run.
Which OS is Best for my Mac
Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.
![Mac Mac](https://www.macworld.co.uk/cmsdata/features/3795660/macos-big-sur-messages-effects-100849703-orig_thumb.jpg)
Should I Upgrade to macOS Catalina or Big Sur?
While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes.
The first issue is compatibility.
Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM.
After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected.
However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.
The second breaking issue is the lack of 32-bit app support.
macOS Catalina and Big Sur can only run 64-bit apps.
If you wondering whether you should upgrade to macOS Catalina or Big Sur, first verify that you don’t have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after the upgrade.
For instance, I had to remove uTorrent after upgrade. And I didn’t know that uTorrent is 32-bit!
How to Know If App is 32-bit or 64-bit
To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:
- Click on Apple logo in the top left corner of the Mac screen
- Click on About This Mac option
- Click on System Report button in Overview tab (first one)
- Scroll down to Software -> Applications
- Find the app and check Kind
Which macOS Should I Use
If you have an older Mac which is not eligible to upgrade with some latest software or hardware, I’d suggest upgrading at least to Sierra (or better High Sierra) for the following reasons:
- Sierra is still supported by Apple, and it gets security updates
- APFS file system is available
- It supports Siri
- Significant security improvements
The most important point when choosing the best OS is the ability to get security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page.
For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan’s end of life date was August 2018.
Snow Leopard Myth
I know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.
Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn’t want to switch to new versions, because the old one was rock solid.
I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs.
After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.
How to Update to the Latest Version
There are two ways to update to the latest OS version on Mac:
- From the Software Update section in System Preferences
- Use a download link
Using Software Update
This is by far the best option, but it only available if you have Yosemite, or later OS installed already. If you enabled automatic updates, then Mac will inform you that the next macOS is available.
Just open System Preferences, go to Software Update and click on the Upgrade Now button.
This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here.
For instance, my the latest version for Mac Mini 2012 is Mojave, I can’t install anything newer than that.
If you are having problems with updates or having issues post-upgrade check my post about troubleshooting macOS.
Using download links
For older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.
After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade.
